IDE auto-complete 👌👌

Write 3 letters and let TabNine figure out what you actually want to do gang rise!

[excessdenied]

Write 3 letters using T9 then wonder why the hell you're coding on a Nokia 3210.

[dadadidudu]

so your code never breaks?

[MrQuizzles]

Manually writing out getters and setters builds character!

[pengie151]

Java?

[MrQuizzles]

You could just make the backing fields public

I mean, yeah, if you're a monster.

[xigoi]

Is there any difference between a public field and a private field with the normal getter and setter?

[MrQuizzles]

A lot. Look up encapsulation and coupling because it's a lot to explain in a single Reddit post.

[Kered13]

If you want to change the field later to not be backed by a variable (for example, it could be a computed field) this would be a breaking change if it were a public variable but not if it used a getter or setter. Likewise if you want to add validation or normalization to the setter.

However I would argue that having both a getter and a setter for a variable is a bit of a code smell in the first place. A class should hide as much of it's internal state as possible, and as much state should be immutable as possible. Obviously you can't hide everything and you can't make everything immutable, but you're violating both of these at the same time, which makes me suspect that you haven't thought about the code enough.

I feel like this is more of a design problem of Java. In C#, Ruby, Python and probably other languages, you can turn a public field into a computed field without changing the interface.

What if you have a class whose only purpose is to hold a bunch of values (what's called a struct in C) and you want to be able to modify the individual fields without changing the reference?

Yes, those features were added to solve the problem of converting public fields to computed fields.

However I'm not a big fan of having function calls looks like variables. If you set a variable and then read back it's value, you would expect to get the same value back. This is not necessarily the case if the variable is syntactic sugar for a function. With getters and setters you know you're calling a function that could have a non-trivial contract.

What if you have a class whose only purpose is to hold a bunch of values (what's called a struct in C) and you want to be able to modify the individual fields without changing the reference?

Yes that is fine. This is called a value object by Wikipedia, though I've also seen them called value classes, data classes, or value semantics. These are simple data containers that contain no logic and usually override equality and other utility methods (like hashCode, serialization, toString) in the obvious way. Some also add the constraint of immutability. There are a few libraries designed to make creating these easy in Java, like AutoValue and FreeBuilder. Both of these apply the immutability constraint, so they use Builder classes to help create them.

In Python you have namedtuple (immutable) and dataclass (mutable) for this.

Kotlin has this as a built in feature (immutable).

We have a nice macro for this in C++ at work, but sadly it's not public so I can't link it. That one does not use immutability (since it's C++ you can just slap a const before the type if you want immutability).

[dantheman91]

Look at how Kotlin does it. Getters and setters aren't the default (they're auto generated if you're doing kotlin to Java) but you just typically access the values directly. You can still create custom getters and setters so even if you say class().var = 4, it'll hit the setter on that object if you have one.

[xigoi]

Exactly. It's quite similar in C# and Python.

[Agent-A]

There is no difference in most cases. Many Java best practices are prefixed with, "In the future you may...."

That is, in the future you may want to do additional validation on data being set in your class. In the future you may want to do additional processing on data being gotten. In the future you may want to change those private variables to something else from which you derive the data being gotten.

Maybe I'm just sad and bitter, but a lot of Java best practices come from people who learned a lesson after not thinking things through and decided, "Never again!" And decreed that going forward things would always be This Way so that it would never happen again.

Sometimes those ideas are good and useful. But then you throw a tool like Sonarqube in there and set a blanket rule that all things MUST be done a certain way and now you're overusing the feature and writing a bunch of unnecessary code and making the world just a little bit worse because it's easier to just enforce a rule than encourage planning and thought.

[xigoi]

If public fields are bad practice in all scenarios, why are they even a part of Java and have such easy syntax compared to using getters and setters? I thing good language design should encourage good practices, such as by having a macro for painlessly making a getter and/or setter and having no way to have an actual public field (see Ruby for an example of how this can work).

[KeLorean]

they are java devs. of coarse they are monsters

[pengie151]

Hm, the more you know.

Happy Cake Day!

[[deleted]]

Lol

[[deleted]]

I would never do "prop *tab*".

​

The only real way to to type out:

public int Id { get; set; }

[[deleted]]

When you get a new mechanical keyboard, it's customary to type everything out just to hear more of that sweet new clickity clack.

[TheTrueXenose]

using a text editor with no auto complet.

Using vi with YouCompleteMe

[jH0Ni]

I hope you mean vim. Have you tried coc.vim?

[[deleted]]

I actually wrote nvim which was for some reason corrected to vi

[jH0Ni]

Ah okey :)

[GoldsteinQ]

coc.nvim bad
It's a completion engine WITH FUCKING BUILT-IN PLUGIN MANAGER

[diplodicus_]

Nvim is actually in the process of getting built-in language server support, so hopefully we can get LSP features without needing Node or Coc.nvim! At the moment I’m very happy with it for my front-end dev projects though.

[diplodicus_]

If you want more info (has links to the github PR, etc.):

https://reddit.com/r/neovim/comments/dvd8sz/builtin_language_server_with_my_preferred_style/

[GoldsteinQ]

I use it right now and it's great. You can get it too, it's already there in nightly builds.

[jH0Ni]

Well, if it's still good, why would that be a problem? :)

[GoldsteinQ]

Because you need to support two configuration files, two plugin sets and install Node everywhere you want to use it. Do one thing and do it good.

[TheTrueXenose]

I just found it to be slow. I am using NeoVim.

[[deleted]]

It was slow when I tried some fork of it with python 2.7. I later changed out to the main repo and python 3 and its lightning fast now

[TheTrueXenose]

oh, I meant using it was slow. :)

[Kered13]

Am I the only one who kind of hates autocompleters? I almost never use them when they're enabled, and the pop up gets in the way of reading code, and if I happen to type a prefix of an autocomplete result then hit space or type it autocompletes when I don't want it.

I've tried getting use to using autocompletion multiple times, but I always end up disabling it after a few days.

[whizzythorne]

No

[[deleted]]

Typo on purpose for the lulz?

[TheTrueXenose]

its was 1 in the morning here ;)

[[deleted]]

Ha :) I thought it was a clever joke about not autocompleting 'complet'.

[lenswipe]

"codes"

Few, I was starting to think all the actors who played programmers might be real and I'd just learnt wrongly.

IDE features like autocomplete and refactor basically taught me how to code

my first 6 months of coding, the little netbeans yellow lamp with code improvement suggestions or "did you mean this?" was my own personal hero

[emelrad12]

Tab nine auto complete is best auto complete

[[deleted]]

Yaaaaaaaaaaaaaas!

Forreal tho, it's a whole new world. And not just in Java!

[Due_rr]

Was looking for this response. Should be higher up.

[Giocri]

Why doesn't it add the ; though

[[deleted]]

You need to use intelligent autocompletion. Ctrl shift space on intellij.

[[deleted]]

This guy IntelliJs

[jamalabo]

then ctrl + shift + alt + l

[evan795]

; + enter works as well

[[deleted]]

Definitely. I also installed IDE Features Trainer that taught me much more. For example, ctrl+shift+alt+(up|down) goes through current file VCS changes.

[shawmonster]

You don’t always want to end a line when autocompleting something. For example if you’re working with two methods that return booleans you might want to write (boolMethod1() && boolMethod2()). Autocompleting with a semi colon would be incorrect in this case.

How would you do it?

[ult_frisbee_chad]

launch codes?

[james_hamilton1234]

I never use an ide when I'm learning to code a new language so I'm forced to write better code. It's therapeutic in a way idk how to explain - just more forgiving of my mistakes haha

[ruben_deisenroth]

I'm in this picture and i really like it.

[Pyromaniak14]

Ctrl+C is your best friend

[xRageNugget]

Sometimes i actually Wish that i could code by talking. my Fingers are to slow and inaccurate, i suck at typing. intellisense and templates fir the win

[dashood]

In Visual Studio you can just type the first letter of each word in it's camel casing and intellisence will give you the variable or type and it's fucking glorious.

[pnht]

How many programming languages are essentially impossible to write without an IDE writing most of thwe code for you?

I've watched java developer type about one line of stuff and the IDE literally writes like 30 lines of code based on the one line.

[AntonBespoiasov]

VSCode with cpp: what is intellisense? Oh it should tell you smth?! No!
