I own got been sharing a lot of roadmaps to perish a Web developer, DevOps engineer, too lately React.js developer. One of the requests I received from many of my readers was for creating a Java Developer Roadmap. Since Java is my expertise, It wasn't a occupation to create a Java Developer Roadmap, but it took slightly longer for me to create 1 because of the limited fourth dimension I get. Anyway, I am in conclusion ready to part my Java developer RoadMap amongst you. This roadmap contains my years of sense too the unobstructed path of how to perish a Java expert. It answers many burning questions similar which technologies a Java developer should learn? What tools brand yous a amend Java developer? And, which framework a Java developer must absolutely learn.
One of the things I tried amongst this roadmap is that to continue the exposure every bit curt every bit possible, I own got avoided mentioning many alternatives, peculiarly when it comes to libraries too tools too stick amongst industry-standard tools too libraries.
I own got kept it uncomplicated thence that most of the people tin dismiss follow it too alone included the essential stuff, but if at that spot is plenty desire, I am thinking to post service The Java Developer RoadMap 2.0 to add together around advanced things similar JVM internals, Profiling, Modules, Cloud Native Java, Containers like Docker too Kubernetes, too much more.
If yous are interested, yous tin dismiss discovery a to a greater extent than exhaustive listing on separate weblog pots, which I own got listed inwards the farther learning section. Anyway, let's perish through this Java Developer RoadMap to empathize how to perish a Java developer inwards 2019.
Btw, yous past times no agency demand to empathize everything on this roadmap to perish a rockstar developer. In fact, yous don’t fifty-fifty demand to own got them that seriously if yous don’t wishing to. Instead, purpose these maps every bit a starting indicate to assistance direct your learning every bit yous go.
1. Git & Github
One of the most pop version command system. It's merely non possible to alive without Git anymore. You tin dismiss banking concern represent out The Git Complete Guide on Udemy to showtime with.
2. Linux
Not merely a spider web developer but for whatever programmer, the Linux command trace of piece of work is very, really important, too I strongly recommend yous to pass around fourth dimension to acquire them. You tin dismiss purpose these free Linux courses to showtime learning Linux.
5. Data Structures too Algorithms
These are the edifice blocks of whatever program, too a goodness noesis of Algorithms too Data Structure is vital for your adjacent task or doing good on your electrical flow situation.
You should at to the lowest degree hold upward familiar amongst essential information structures similar an array, linked list, hash table, binary tree, queue, stack, too graph.
If yous know advanced information structures similar Trie, B-Tree, AVL tree, too thence it's good too good. But, if yous don't know too thence I advise yous to bring together a comprehensive course of pedagogy similar Data Structures too Algorithms: Deep Dive Using Java, which volition learn yous everything almost all those fundamentals.
3. HTTP / HTTPS
The HTTP protocol is the backbone of the web, too a goodness noesis of both HTTP too HTTPS is mandatory for a spider web developer
7. Computer Science Fundamentals
If yous are creating global applications that demo information inwards many unlike languages across the world, too thence yous should own got a goodness noesis of grapheme encodings. It basically tells your browser how to demo your data.
8. Design Patterns
There is no uncertainty that every programmer should know Git too Github every bit they are the criterion inwards price of version command too code repository. If yous wishing to acquire too master copy Git too Github, yous tin dismiss banking concern represent this listing of books and courses to acquire Design patterns.
The instant business office is the create tool, which yous demand to create too deploy your projects similar Gradle. Anyone of this would hold upward enough. I own got merely listed ANT, but that's for legacy projects. For all novel Java projects, prefer Maven or Gradle.
If yous are interested inwards learning almost these tools, hither are around useful courses to acquire create tools too IDEs
At to the lowest degree yous should know almost all everyday objects similar ArrayList, HashMap, HashSet, LinkedHashSet, TreeSet, etc. Each of them has their unlike holding similar ArrayList is a dynamic array which tin dismiss grow, HashMap is a criterion implementation of the hash tabular array too tin dismiss hold upward used to shop key-value pairs.
Similarly, HashSet is a laid implementation that doesn't allow duplicate elements. I strongly advise yous check
On the other hand, if the toll is an issue, yous tin dismiss also banking concern represent this Udemy course of pedagogy to Efficient Java Multithreading amongst Executors, which won't cost yous to a greater extent than than $10 if yous acquire it on Udemy flash sales which happens every month. This is also an splendid course of pedagogy to acquire Java concurrency too multithreading inwards Java.
If yous own got to code a real-world, meat Java application, yous volition demand to purpose classes similar File, InputStream, OutputStream, Reader, Writer from java.io package, which is the meat of the Java IO API. Similarly, yous also demand to know almost ByteBuffer, FileChannel, Selector, too other critical classes from the java.nio API, if yous wishing to write a socket-based application.
Unfortunately, at that spot are non many dedicated resources on teaching Java IO too Java NIO API, but The Complete Java Masterclass is a corking resources to master copy this API. You volition discovery a lot of essential concepts from this API inwards this course.
Now, the adjacent too around other necessary API, a Java programmer, should acquire is the Java 8 features, which has completely changed the way Java is coded too programmed nowadays. In lodge to perish a Java developer inwards 2019, yous must know how to purpose a Lambda expression, Stream API, Optional classes, too novel Date too Time API.One of the things I tried amongst this roadmap is that to continue the exposure every bit curt every bit possible, I own got avoided mentioning many alternatives, peculiarly when it comes to libraries too tools too stick amongst industry-standard tools too libraries.
I own got kept it uncomplicated thence that most of the people tin dismiss follow it too alone included the essential stuff, but if at that spot is plenty desire, I am thinking to post service The Java Developer RoadMap 2.0 to add together around advanced things similar JVM internals, Profiling, Modules, Cloud Native Java, Containers like Docker too Kubernetes, too much more.
If yous are interested, yous tin dismiss discovery a to a greater extent than exhaustive listing on separate weblog pots, which I own got listed inwards the farther learning section. Anyway, let's perish through this Java Developer RoadMap to empathize how to perish a Java developer inwards 2019.
Btw, yous past times no agency demand to empathize everything on this roadmap to perish a rockstar developer. In fact, yous don’t fifty-fifty demand to own got them that seriously if yous don’t wishing to. Instead, purpose these maps every bit a starting indicate to assistance direct your learning every bit yous go.
Mandatory science for whatever Java developers
1. Git & Github
One of the most pop version command system. It's merely non possible to alive without Git anymore. You tin dismiss banking concern represent out The Git Complete Guide on Udemy to showtime with.
2. Linux
Not merely a spider web developer but for whatever programmer, the Linux command trace of piece of work is very, really important, too I strongly recommend yous to pass around fourth dimension to acquire them. You tin dismiss purpose these free Linux courses to showtime learning Linux.
5. Data Structures too Algorithms
These are the edifice blocks of whatever program, too a goodness noesis of Algorithms too Data Structure is vital for your adjacent task or doing good on your electrical flow situation.
You should at to the lowest degree hold upward familiar amongst essential information structures similar an array, linked list, hash table, binary tree, queue, stack, too graph.
If yous know advanced information structures similar Trie, B-Tree, AVL tree, too thence it's good too good. But, if yous don't know too thence I advise yous to bring together a comprehensive course of pedagogy similar Data Structures too Algorithms: Deep Dive Using Java, which volition learn yous everything almost all those fundamentals.
3. HTTP / HTTPS
The HTTP protocol is the backbone of the web, too a goodness noesis of both HTTP too HTTPS is mandatory for a spider web developer
7. Computer Science Fundamentals
If yous are creating global applications that demo information inwards many unlike languages across the world, too thence yous should own got a goodness noesis of grapheme encodings. It basically tells your browser how to demo your data.
8. Design Patterns
There is no uncertainty that every programmer should know Git too Github every bit they are the criterion inwards price of version command too code repository. If yous wishing to acquire too master copy Git too Github, yous tin dismiss banking concern represent this listing of books and courses to acquire Design patterns.
The Complete Java Developer RoadMap
Now, let's explore this Java developer roadmap together too discovery out what tools, frameworks, libraries, APIs yous tin dismiss learn1. Tools
The tools department is divided into 2 principal parts. First, your IDE, which is your primary tool too tin dismiss practise almost everything yous asked for similar compile, run, debug, profile, test, compare files too code, refactoring, too much more.The instant business office is the create tool, which yous demand to create too deploy your projects similar Gradle. Anyone of this would hold upward enough. I own got merely listed ANT, but that's for legacy projects. For all novel Java projects, prefer Maven or Gradle.
If yous are interested inwards learning almost these tools, hither are around useful courses to acquire create tools too IDEs
- 5 courses to acquire Apache Maven for Java developers
- 5 Courses to acquire IntelliJIDEA
- 5 Free Courses to acquire Eclipse IDE
2. JDK APIs
The adjacent of import matter to acquire is JDK APIs, which is very, really of import for whatever Java developer. This is quite a big section, too that's why it's divided into meat areas similar Java Collections framework, Java Concurrency, Java IO, too Java 8 APIs, let's explore each of them
2.1 Java Collections Framework
This is 1 of the most essential Java API every Java developer should learn. This API provides implementations of criterion information construction inwards Java-like linked list, set, stack, queue, hash table, priority queue, too others.At to the lowest degree yous should know almost all everyday objects similar ArrayList, HashMap, HashSet, LinkedHashSet, TreeSet, etc. Each of them has their unlike holding similar ArrayList is a dynamic array which tin dismiss grow, HashMap is a criterion implementation of the hash tabular array too tin dismiss hold upward used to shop key-value pairs.
Similarly, HashSet is a laid implementation that doesn't allow duplicate elements. I strongly advise yous check
On the other hand, if the toll is an issue, yous tin dismiss also banking concern represent this Udemy course of pedagogy to Efficient Java Multithreading amongst Executors, which won't cost yous to a greater extent than than $10 if yous acquire it on Udemy flash sales which happens every month. This is also an splendid course of pedagogy to acquire Java concurrency too multithreading inwards Java.
2.3 Java IO
I own got interviewed to a greater extent than than 100+ Java programmers, too I own got noticed 1 pattern; they all own got really fiddling noesis of Java IO too NIO APIs every bit compared to Java Collections too Java Multithreading API. I tin dismiss empathize that many people pass a lot of fourth dimension learning those 2 APIs, but yous cannot exit behind this critical APIs.If yous own got to code a real-world, meat Java application, yous volition demand to purpose classes similar File, InputStream, OutputStream, Reader, Writer from java.io package, which is the meat of the Java IO API. Similarly, yous also demand to know almost ByteBuffer, FileChannel, Selector, too other critical classes from the java.nio API, if yous wishing to write a socket-based application.
Unfortunately, at that spot are non many dedicated resources on teaching Java IO too Java NIO API, but The Complete Java Masterclass is a corking resources to master copy this API. You volition discovery a lot of essential concepts from this API inwards this course.
2.4 Java 8 Features
Without knowing these APIs, it would hold upward really tough to write a Java application inwards 2019. Most of the library also instantly halt supporting version lower than Java 8, which agency yous own got to acquire Java 8 features instantly than later. It's already five years since Java 8 was released, thence yous literally own got no excuse left.
When it comes to learning Java 8 features, at that spot are a lot of splendid resources available inwards the market, but if yous already know Java, I advise yous select the resources which alone focuses on Java 8 features similar
3.2 Hibernate
The instant framework which I recommend every Java developer to acquire is the Hibernate, which is based upon JPA (Java Persistence API). To hold upward accurate, Hibernate came earlier JPA, but because JPA is criterion API to implement the persistence layer inwards Java, Hibernate implements it.Now, why should yous acquire Hibernate? Well, because most of the Java applications yous volition operate amongst volition interact amongst Database, too it's excruciating to bargain amongst Database inwards Java using JDBC too without a proper framework similar Hibernate.
It provides around of the essential features similar Caching too Transaction out-of-the-box, which agency yous own got to a greater extent than fourth dimension to focus on your application logic, too thence implementing caching inwards your application. This seriously improves the functioning of Java application, too thence far, my most meaning argue to purpose Hibernate.
Now, when it comes to learning Hibernate at that spot are many corking resources available inwards the market, but the Spring & Hibernate for Beginners course of pedagogy is my preferred 1 because yous tin dismiss kill 2 birds from 1 stone, yous tin dismiss acquire both Spring too Hibernate inwards 1 course of pedagogy rather than joining separate courses for them.
3.3 Spring Boot
This is around other framework I recommend every Java developer to acquire inwards 2019 too going forward. Spring Boot took Spring's philosophy of simplification too made it like shooting fish in a barrel to operate amongst Spring itself. Just similar Spring makes it easier to create a Java application, Spring Boot makes it easier to create a spring-based Java application.Features similar auto-configuration own got away most of the hurting associated amongst configuring Spring application. Similarly, starter POM features grouped unremarkably used dependency into uncomplicated reusable POMs.
Now, if yous wishing to acquire Spring Boot, I strongly advise yous perish through Learn Spring Boot inwards 100 Steps course; it's 1 of the best too most up-to-date too also render step-by-step guides for mutual things a Spring Boot developer needs to know.
4. Testing
Testing is an essential science for whatever Java developer, peculiarly unit of measurement testing, integration testing, too automation testing. At the bare minimum, every Java developer should hold upward familiar amongst JUnit too Mockito, 2 of the most pop Unit testing too Mock library.If yous know these 2 too know how to purpose them to effectively create a unit of measurement test, yous volition hold upward a much amend Java developer than without them.
There are to a greater extent than advanced libraries also exists similar Cucumber for Business-driven testing, Robot Framework for integration testing, but at that spot is no substitute for JUnit, yous volition e'er demand that.
When it comes to a mocking library, yous own got a pair of choices similar PowerMock, Mockito, too EasyMock, but I strongly advise yous acquire Mockito because it's a corking library too also many Java developers too companies are doing that. It is tardily becoming the criterion library for creating mock objects inwards Java.
If yous wishing to acquire JUnit too Mockito, I own got already shared a lot of resources similar books too courses, yous tin dismiss banking concern represent those to acquire more.
5. Utility Libraries
The existent ability of Java lies inwards its rich ecosystem of opened upward source libraries. You volition discovery libraries to practise almost anything inwards Java from logging to machine learning, from sending an HTTP asking to parsing JSON too much more.Apart from that, Java is also lucky to own got utility libraries similar Apache Commons too Google Guava, these 2 libraries effectively complement JDK libraries. I own got also shared a listing of 20 Java APIs too libraries for Java developers.
I advise yous perish through that list, chances are that yous already one-half of them but if yous don't acquire them they are very, really useful too assistance yous to write amend Java programs too deliver faster.
That's all almost the 2019 Java Developer Roadmap. This is an splendid resources to acquire Java inwards 2019 too perish a amend Java developer. I own got kept it uncomplicated thence that most of the people tin dismiss follow it too alone included the vital stuff, but if at that spot is plenty desire, I am thinking to post service The Java Developer RoadMap 2.0 to include around advanced materials similar JVM internals, Profiling, Modules, Cloud Native Java, Containers too much more.
