One of the oldest coding exercise is to buy the farm along trouble width 80, as well as many of us follow it blindly but accept you lot always idea why nosotros accept this exercise inwards get-go place? I believe it was to brand your code to a greater extent than readable inwards the historic stream of small-scale monitors thence that whole content tin lucifer inwards the screen, or it mightiness accept originated from the historic stream of punch card, which was used to endure lxxx column wide. This sounds reasonable when nosotros intend close those quondam days but do you lot intend this dominion makes feel inwards 2019? We are at in 1 lawsuit living inwards the historic stream where most of the developers accept got large monitors, which tin exhibit up-to 180 characters, doesn't this is wastage of precious monitor space? It also makes your code unnecessary long, as well as thence it genuinely is.
I get-go come upwardly to know close trouble wrapping at 80, piece reading Oracle Code Conventions for the Java Programming Language, which was in conclusion revised at Apr 20, 1999, which nether indentation says

If I understood correctly (I may endure wrong), 1 finish of this dominion is consistency. I used to intend that lxxx was silly, but existence able to larn through source code written past times a dozen unlike teams over in conclusion vii years as well as non needing to re-size my window is a genuinely overnice thing. Consistent column width helps amongst the mensuration of reading code.
Since I mostly worked amongst large monitors, similar LG 32MP58HQ-P 32-Inch IPS Monitor with Screen Split, I also realize that nosotros are wasting lots of precious space. The consistent column width of lxxx is but every bit good little. I personally purpose 120 unless the projection I operate already finalized a column width, inwards that case, I larn for consistency.
One to a greater extent than argue people give for withal using a column amongst of lxxx is that present they are working amongst multiple files at once. For example, if you lot purpose touchstone column width you lot tin lucifer a duo of files across a argue as well as tin compare them trouble past times line, which I believe is a existent benefit.
You tin fifty-fifty do a three-way merge inspection on 1 covert without scrolling sideways. By the way, this should non endure done at toll of excessive wrapping. I sympathise that consistent columns larn inwards easier to scan as well as read through text but it doesn't affair whether it's lxxx or 120.
On a closing note, I would country that consistency is overnice as well as you lot must larn for it but lxxx or fifty-fifty 100 is every bit good short. Many developers could belike alive amongst 120 or fifty-fifty 150 though. Our modern widescreen high Definition LCD monitors tin easily handgrip more.
It is much to a greater extent than readable than the excessive wrapping because I personally notice it much harder to read a wrapped trouble than precisely seeing the whole thing inwards 1 line. Of course, this is precisely preference as well as others volition experience different.

4.1 Line Length
Avoid lines longer than lxxx characters, since they're non handled good past times many terminals as well as tools.
Note: Examples for purpose inwards documentation should accept a shorter trouble length-generally no to a greater extent than than seventy characters.
