One of the questions my reader ofttimes inquire me is, shall I acquire Scala? Does Scala has a amend futurity than Java, or why Java developer should acquire Scala together with thence on. Well, at that topographic point tin live on many reasons for learning Scala, e.g., you lot are forced to acquire because it been used inwards the novel fellowship you lot joined or your solution architect decided to usage it, but that's a dissimilar story. Here, we'll utter virtually reasons which encourage Java developers to acquire Scala. Scala has emerged every bit 1 of the most powerful Java alternatives inwards recent times. It's been the JVM linguistic communication of choice, leaving Groovy together with Clojure way behind, together with preferred every bit the linguistic communication people desire to write most code in.
Scala has several strong points, strongest existence the multi-paradigm language. With the superiority of functional programming idioms to receive got wages of multi-core CPU architecture, Scala has the correct mix of the pop object-oriented paradigm.
It non exclusively solves many of Java issues, e.g. less to no boilerplate but also provides several best practices together with patterns, correct from the language. Despite providing fluency together with flexibility of dynamic linguistic communication similar Python, it's nevertheless a strongly statically typed linguistic communication to preclude you lot from doing bad things, which simply come about at runtime inwards instance of a dynamic language.
I am sure Scala developers volition add together many to a greater extent than reasons into this list, but existence from Java background together with ardent supporter of Java, I think Scala definitely got something to offer, together with the next reasons brand a lot of cases for Java developers to acquire Scala.
The Pragmatic Programmer mass also advised you lot to acquire a novel programming linguistic communication every year. Scala allows you lot to define types associated amongst both information attributes (with classes behaving similar C++/Java classes) together with conduct attributes (with traits corresponding to Java interfaces).
Just similar inwards other functional programming languages, Scala functions are splendid (which way you lot tin travel past times them roughly every bit values), together with Scala also supports anonymous functions together with currying (partial application of multi-argument functions).
This combination of features makes it possible to write Scala programs that are quite concise together with elegant. Being multi-paradigm is 1 of the strongest selling points of Scala, which Java 8 has also attempted past times introducing lambda expressions (see Java SE 8 New Features), but it nevertheless a distich of steps behind. I think Scala volition e'er live on to a greater extent than functional than Java, but that's the theme of some other debate.
Given, many Java developers are turning into Scala, this is the perfect way of leveraging their years of experience inwards real-world programming. It is also possible to telephone telephone Scala code from Java, together with you lot tin easily write portion of your plan inwards Scala together with the remainder inwards Java.
In short, Interoperability amongst Java gives Scala a huge potential to acquire mainstream, firm programming language, every bit thence much of the world's code is written inwards Java, together with thence many developers are working inwards Java roughly the world.
Several of best practices together with patterns are built into the linguistic communication itself, e.g. val declares top-level immutability, which is much amend than the overloaded concluding inwards Java, or const/read-only inwards C# amongst the weird rules associated amongst it.
Scala also offers closures, a characteristic that dynamic languages similar Python together with Ruby receive got adopted from the functional programming paradigm.
To plough over you lot an idea, hither is the give-and-take count plan written inwards both Java together with Scala, you lot tin run into the divergence inwards the expressiveness of linguistic communication past times yourself. Scala has achieved inwards simply 1 business what Java has taken to a greater extent than than 10 lines to achieve.
Btw, things tin live on improved on Java side past times using Java 8 features, which is non used inwards this example, but still, Scala scores large over Java when it comes to concise together with create clean code.
Given Scala's marketing every bit Scalable language, days are non far when the large Investment banks together with Financial organizations volition start looking Scala for their depression latency solutions. Similar to the advice given in Effective Java, Twitter has already shared best practices to prepare programs inwards Scala every bit Effective Scala.
The founders of Quora spent a distich of months edifice a Scala spider web framework inwards gild to usage Scala. Martin Odersky, the human being behind Scala, is straight off behind the start-up Typesafe for supporting commercial Scala development. All things are going inwards the correct direction for Scala to grow every bit the foremost alternative to Java.
Scala is the best of both worlds. It feels similar dynamic, but its strongly statically typed languages, e.g. Haskell or Java. Scala compiler is actually smart together with uses type-inference upward to the sum extent.
Scala provides type inference for variables together with functions, much amend than limited type inference inwards Java together with C#. See Beginning Scala Programming learn to a greater extent than virtually Scala linguistic communication features.
There are some prissy Scala spider web frameworks out there, including Lift together with Play. Akka, some other Scala-based concurrent framework, has already established itself every bit toolkit together with runtime for edifice highly concurrent, distributed, together with fault-tolerant event-driven applications on the JVM.
Scala is also existence used inwards Big information infinite along amongst Apache Spark, which has farther fuelled its adoption past times many Java developers interested inwards Big Data Space.
More together with to a greater extent than IDEs are started to back upward Scala syntax, much amend back upward inwards Eclipse together with IntelliJ. Great create tool back upward inwards SBT, Maven, together with Ant. Well, Part of this is because of Scala's capability every bit existence a language, which tin live on every bit terse every bit many dynamic languages similar python, at the same fourth dimension tin offering features similar static typing, type-inference, a mix of functional programming together with object-oriented programming.
In Recent surveys, Scala is also touted every bit the number 1 alternative of Java. In my opinion, to grow Scala has the existent alternative of Java, given Java 8 also has functional programming support, it has to attract to a greater extent than together with to a greater extent than Java developers. Getting a large scheme similar Twitter to adopt Scala, for sure helps the community, every bit they receive got to a greater extent than resources together with influence.
Java has long been criticized for his verbose together with boilerplate syntax. Though it makes Java to a greater extent than readable, much similar English, Scala has laid a novel benchmark inwards existence concise together with readable at the same time. Scala compiler, known every bit a scalar (remember javac), does to a greater extent than than you lot expect; it tin generate toString(), equals(), hasCode(), together with other things for you. Consider ii code snippets of the same course of report written inwards Java together with Scala together with brand your selection :
public course of report Book {
someone concluding String name;
someone concluding double price;
populace Star(String name, double price) {
this.name = name;
this.price = price;
}
@Override
populace int hashCode() {
int hash = 7;
hash = 23 * hash + Objects.hashCode(this.name);
render hash;
}
@Override
populace boolean equals(Object obj) {
if (obj == null) {
render false;
}
if (getClass() != obj.getClass()) {
render false;
}
concluding Test other = (Test) obj;
if (!Objects.equals(this.name, other.name)) {
render false;
}
if (Double.doubleToLongBits(this.price) != Double.doubleToLongBits(other.price)) {
render false;
}
render true;
}
@Override
populace String toString() {
render "Test{" + "name=" + cite + ", price=" + toll + '}';
}
}
You tin write the same thing, using Scala's instance course of report every bit below :
case course of report Book(name: String, price: double)
Btw, you lot tin also usage Lombok library, 1 of the essential libraries for Java developers, to take the boilerplate code related to getter, setter, equals, hashCode, together with toString. It tin automatically generate those for you.
While taking their fourth dimension to acquire Functional Programming, Java developer tin nevertheless live on productive inwards Scala past times leveraging their existing noesis of OOP. Like Java, Scala has create clean syntax, prissy libraries, adept online documentation, together with lots of people inwards the manufacture using it.
With a growing community of Scala at forums, StackOverflow, it's non hard to notice an answer to whatever Scala questions, which adds to your learning experience.
That's all virtually Why Java programmers should acquire Scala or some practical Reasons for learning Scala programming language. I am sure you lot volition notice many to a greater extent than reasons, 1 time you lot start exploring it. Once you lot start learning Scala, I am sure you lot volition LOVE IT. It non exclusively got the cleaner OO code but also Functional capabilities; it feels dynamic (Like Python) but also has a static type scheme that tin preclude you lot from doing bad things. If you lot decided to acquire Scala inwards 2018, hither are some of the useful resources for farther learning

Thanks for reading this article thence far. If you lot similar Scala together with notice my reasons helpful, together with then delight part it amongst your friends together with colleagues. If you lot receive got whatever to a greater extent than reasons to add together to this list, experience costless to driblet a note.
Scala has several strong points, strongest existence the multi-paradigm language. With the superiority of functional programming idioms to receive got wages of multi-core CPU architecture, Scala has the correct mix of the pop object-oriented paradigm.

I am sure Scala developers volition add together many to a greater extent than reasons into this list, but existence from Java background together with ardent supporter of Java, I think Scala definitely got something to offer, together with the next reasons brand a lot of cases for Java developers to acquire Scala.
10 Reasons to acquire Scala Programming Language
Here are some of the reasons I think Java programmers or per se whatever programmer should acquire Scala:1) Multi-Paradigm language
Scala is a fleck dissimilar than Java, every bit it supports ii programming paradigms: object-oriented programming (OOP) together with functional programming (FP). For advancing inwards programming skills, it's adept to acquire at to the lowest degree 1 linguistic communication from dissimilar paradigms, e.g. imperative, logical, functional, together with OOP, together with Scala gives you lot a run a jeopardy to explore both functional together with oop together.The Pragmatic Programmer mass also advised you lot to acquire a novel programming linguistic communication every year. Scala allows you lot to define types associated amongst both information attributes (with classes behaving similar C++/Java classes) together with conduct attributes (with traits corresponding to Java interfaces).
Just similar inwards other functional programming languages, Scala functions are splendid (which way you lot tin travel past times them roughly every bit values), together with Scala also supports anonymous functions together with currying (partial application of multi-argument functions).
This combination of features makes it possible to write Scala programs that are quite concise together with elegant. Being multi-paradigm is 1 of the strongest selling points of Scala, which Java 8 has also attempted past times introducing lambda expressions (see Java SE 8 New Features), but it nevertheless a distich of steps behind. I think Scala volition e'er live on to a greater extent than functional than Java, but that's the theme of some other debate.
2) Interoperability amongst Java
In my opinion, Scala's selection of existence interoperable amongst Java is the best affair to come about to Scala. Scala runs on the Java Virtual Machine (JVM) together with tin interoperate nicely amongst Java code. This way Scala developers tin usage Java libraries direct from Scala code.Given, many Java developers are turning into Scala, this is the perfect way of leveraging their years of experience inwards real-world programming. It is also possible to telephone telephone Scala code from Java, together with you lot tin easily write portion of your plan inwards Scala together with the remainder inwards Java.
In short, Interoperability amongst Java gives Scala a huge potential to acquire mainstream, firm programming language, every bit thence much of the world's code is written inwards Java, together with thence many developers are working inwards Java roughly the world.
3) Best Practices together with Patterns built-in language
One affair you lot mightiness non know virtually Scala that it was originally developed at the Swiss academy EPFL inwards an endeavour to apply recent innovations inwards programming languages enquiry to a linguistic communication that tin gain mainstream traction, much similar Java.Several of best practices together with patterns are built into the linguistic communication itself, e.g. val declares top-level immutability, which is much amend than the overloaded concluding inwards Java, or const/read-only inwards C# amongst the weird rules associated amongst it.
Scala also offers closures, a characteristic that dynamic languages similar Python together with Ruby receive got adopted from the functional programming paradigm.
4) Expressiveness of language
When you lot compare Scala amongst Java every bit I did inwards my previous post service virtually the difference betwixt Scala together with Java, Scala for sure scores large over Java. Scala is inherently real expressive. There’s also tons together with tons of actually beautiful together with useful code written inwards Scala. This is attracting to a greater extent than together with to a greater extent than Java developers to acquire Scala, who similar such beautiful code.To plough over you lot an idea, hither is the give-and-take count plan written inwards both Java together with Scala, you lot tin run into the divergence inwards the expressiveness of linguistic communication past times yourself. Scala has achieved inwards simply 1 business what Java has taken to a greater extent than than 10 lines to achieve.
Btw, things tin live on improved on Java side past times using Java 8 features, which is non used inwards this example, but still, Scala scores large over Java when it comes to concise together with create clean code.
5) Marketable
Which programmer doesn't desire to live on marketable? One argue for learning a novel technology scientific discipline or framework is e'er a amend chore together with career growth. Learning Scala volition for sure brand you lot to a greater extent than marketable. Many companies are using or migrating to Scala these days, including Twitter, LinkedIn, Foursquare, together with Quora.Given Scala's marketing every bit Scalable language, days are non far when the large Investment banks together with Financial organizations volition start looking Scala for their depression latency solutions. Similar to the advice given in Effective Java, Twitter has already shared best practices to prepare programs inwards Scala every bit Effective Scala.
The founders of Quora spent a distich of months edifice a Scala spider web framework inwards gild to usage Scala. Martin Odersky, the human being behind Scala, is straight off behind the start-up Typesafe for supporting commercial Scala development. All things are going inwards the correct direction for Scala to grow every bit the foremost alternative to Java.
6) Statically typed language
In general, statically typed linguistic communication similar Java prevents programmers from doing bad things, piece amongst a dynamic linguistic communication similar Python, you lot exclusively know virtually a bad affair when you lot run the program.Scala is the best of both worlds. It feels similar dynamic, but its strongly statically typed languages, e.g. Haskell or Java. Scala compiler is actually smart together with uses type-inference upward to the sum extent.
Scala provides type inference for variables together with functions, much amend than limited type inference inwards Java together with C#. See Beginning Scala Programming learn to a greater extent than virtually Scala linguistic communication features.
8) Growing Framework, e.g. Akka, Play, together with Spark
One affair which you lot mightiness know that Scala is growing together with it's growing real well. Lots of adept libraries, frameworks are coming around. Companies who receive got started using Scala are also contributing to the recent increment of Scala every bit a mainstream language.There are some prissy Scala spider web frameworks out there, including Lift together with Play. Akka, some other Scala-based concurrent framework, has already established itself every bit toolkit together with runtime for edifice highly concurrent, distributed, together with fault-tolerant event-driven applications on the JVM.
Scala is also existence used inwards Big information infinite along amongst Apache Spark, which has farther fuelled its adoption past times many Java developers interested inwards Big Data Space.
7) Growing Community
Along amongst language, the Scala community is also growing together with growing real fast. Lots of programmers, including Java developers, are joining the Scala bandwagon. More together with to a greater extent than frameworks, libraries are getting built on Scala.More together with to a greater extent than IDEs are started to back upward Scala syntax, much amend back upward inwards Eclipse together with IntelliJ. Great create tool back upward inwards SBT, Maven, together with Ant. Well, Part of this is because of Scala's capability every bit existence a language, which tin live on every bit terse every bit many dynamic languages similar python, at the same fourth dimension tin offering features similar static typing, type-inference, a mix of functional programming together with object-oriented programming.
In Recent surveys, Scala is also touted every bit the number 1 alternative of Java. In my opinion, to grow Scala has the existent alternative of Java, given Java 8 also has functional programming support, it has to attract to a greater extent than together with to a greater extent than Java developers. Getting a large scheme similar Twitter to adopt Scala, for sure helps the community, every bit they receive got to a greater extent than resources together with influence.
9) Concise Syntax
Java has long been criticized for his verbose together with boilerplate syntax. Though it makes Java to a greater extent than readable, much similar English, Scala has laid a novel benchmark inwards existence concise together with readable at the same time. Scala compiler, known every bit a scalar (remember javac), does to a greater extent than than you lot expect; it tin generate toString(), equals(), hasCode(), together with other things for you. Consider ii code snippets of the same course of report written inwards Java together with Scala together with brand your selection :
public course of report Book {
someone concluding String name;
someone concluding double price;
populace Star(String name, double price) {
this.name = name;
this.price = price;
}
@Override
populace int hashCode() {
int hash = 7;
hash = 23 * hash + Objects.hashCode(this.name);
render hash;
}
@Override
populace boolean equals(Object obj) {
if (obj == null) {
render false;
}
if (getClass() != obj.getClass()) {
render false;
}
concluding Test other = (Test) obj;
if (!Objects.equals(this.name, other.name)) {
render false;
}
if (Double.doubleToLongBits(this.price) != Double.doubleToLongBits(other.price)) {
render false;
}
render true;
}
@Override
populace String toString() {
render "Test{" + "name=" + cite + ", price=" + toll + '}';
}
}
You tin write the same thing, using Scala's instance course of report every bit below :
case course of report Book(name: String, price: double)
Btw, you lot tin also usage Lombok library, 1 of the essential libraries for Java developers, to take the boilerplate code related to getter, setter, equals, hashCode, together with toString. It tin automatically generate those for you.
10) Relative Easy to learn
For a Java developer learning a classical functional programming linguistic communication similar Haskell or OCaml is rather hard than Scala; inwards other words, Scala is relatively slow to acquire because of its oop functionality.While taking their fourth dimension to acquire Functional Programming, Java developer tin nevertheless live on productive inwards Scala past times leveraging their existing noesis of OOP. Like Java, Scala has create clean syntax, prissy libraries, adept online documentation, together with lots of people inwards the manufacture using it.
With a growing community of Scala at forums, StackOverflow, it's non hard to notice an answer to whatever Scala questions, which adds to your learning experience.
That's all virtually Why Java programmers should acquire Scala or some practical Reasons for learning Scala programming language. I am sure you lot volition notice many to a greater extent than reasons, 1 time you lot start exploring it. Once you lot start learning Scala, I am sure you lot volition LOVE IT. It non exclusively got the cleaner OO code but also Functional capabilities; it feels dynamic (Like Python) but also has a static type scheme that tin preclude you lot from doing bad things. If you lot decided to acquire Scala inwards 2018, hither are some of the useful resources for farther learning
