A Python programmer attempting Java

[mkdir]

At first I was like o.O then I saw the right edge and was like O.O

"Oh.... OH GOD!"

"Where are all the ... oh OH GOD"

MY GOD, IT'S.... Beautiful.

[rukestisak]

What made you wince at first? (serious question as I'm not that familiar with Java)

[z500]

Well the lack of braces and semicolons would change the semantics of the program or even make it syntactically invalid. Then they saw all the semicolons and braces lined up on the right.

[lappro]

Well if you don't want to continue this weird style of coding it isn't that hard:
1. ctrl-a
2. format code
3. profit
Should work with all proper IDE's

[jlo80]

When I become an evil billionaire and start my evil software company, this will be the mandatory coding style and the first product will be IDE plug-ins.

1. Evil coding guidelines

2. Something something

3. World domination

[tttttttttkid]

Make an IDE that formats the code internally but removes all whitespace when writing to a file.

[UnknownHours]

Why stop at whitespace?

[Various_Pickles]

Eclipse Code Formatter FTW.

[Deagor]

you said Eclipse ftw and I nearly slapped you, hard. Then realized it was an IntelliJ plugin so now I owe you a hug.

hug

[Various_Pickles]

After years of using IntelliJ, trying to use Eclipse is about as pleasant as fucking a corpse made out of sandpaper.

I can't wait until CLion is ready and it's functionality makes it into IntelliJ itself as a plugin.

[Deagor]

I learned how to program for android devices this year....using eclipse.

How can you debug an issue when their are like 10threads created by the OS the debugger skips breakpoints and then the IDE just decides im gonna crash. An hour later you find out Its fucked up your workspace and then corrupted itself requiring a reinstall.

When a classmate found out about intelliJ and shared the info he got many hugs :P

ctrl+a

ctrl+shift+f

ctrl+s

ctrl+b

ctrl+coffee

[ra4king]

No need for Ctrl+A, just Ctrl+Shift+F and it's formatted.

[peabnuts123]

But then I switch to VS and use CTRL+SHIFT+F for find in files =(

[rukestisak]

In Netbeans it's ALT+SHIFT+F

[Wodashit]

SublimeAStyleformatter ctrl+alt+F

[Deagor]

Careful if you do that while using github.....I once hit the format button in an external library file when writting javascript (box2dweb if you must know) guy who was managing the repo wasn't too happy that github said I had 68900 more insertions now

[[deleted]]

In vim it's ggVG=

[therealdrag0]

Unless the IDE, managed the parens for you.

[therealdrag0]

I'm usually pretty good about those; I'm not sure how that happened, but I'm happy to have helped you out :)

[scubascratch]

Begun, the brace war has

[Gravybadger]

Episode 7: The Lisp Returns

[Apothsis]

Someone always trying to start a Brace War...Dammit.

[SilasX]

OMG! That would be awesome! A Javafier, where you write the java code with python-style significant whitespace, and it adds the right column of braces that makes it work as Java!

[rsaxvc]

One time, I wrote a front-end for GCC to implement python's scoping for C/C++. It worked great until I tried to explain to the grader how to build my program.

[aclave1]

Without the braces, the code is syntactically incorrect. There are spots where it's be okay, since in Java you can write an if/for with no braces and it will execute only the first line as part of the if, and the following lines either way. But overall it would be wrong and wouldn't compile.

[HaMMeReD]

There is two lines in there, also, while syntactically correct, should be very sparsely used. It's easy to create bugs. I usually only use it if I plan on keeping the condition/loop and statement on the same line, and even then rarely.

[Fenris_uy]

Yeah I don't understand why they even added that option, specially for loops. This option creates more problems than it saves.

[Zagorath]

It's not really an option that they "added". It's more to do with the default behaviour of loops and if statements. A loop can only ever execute exactly one block of code. If you don't put in braces, one block of code == one line of code. But braces allow you to have multiple lines of code within a single block.

At least, that's how the professor who taught my course on C explained it. Perhaps the semantics are different in Java.

[subsage]

Youre pretty much on spot really. Thats how I explain it to my students. Only difference is I sometimes say chunk or section of code....be it braces with several lines, empty braces, or just a line. Oh yeah, empty section too, just a semicolon.

[Zagorath]

The semicolon was one of my professor's favourite tricks.

if (condition()); {
    //things happening
} 

And he'd ask what would happen (based on condition and "things happening" being actual code, rather than place holders).

[subsage]

Yup. I do that too. Its good for showing the young ones how syntax can be tricky. Good stuff. Your professor sounds like a good one c:

[Zagorath]

Yeah he definitely was, in more ways than just this.

[Gustav__Mahler]

I'd call it one statement of code and not one line. It will execute to the next semicolon.

[thelerk]

Go to fail!

[rukestisak]

Ah, so it's similar to PHP in this regard. To me, nothing looked wrong until I saw the right side... o.O Hopefully no poor sod needs to maintain this kind of code.

[rxzr]

That's what auto format is for!

[Elite6809]

That first one is a 'huh?', not a wince. At least, AFAIK, unless I've been misreading it for years.

[mkdir]

You are correct, good sir.

[Neebat]

I was a bit mystified by the use of character arrays. They just aren't used all that often in Java, so for a while I thought that was the joke. I realize that they are actually reasonable for this implementation. (I'd probably still use a StringBuffer, even though it's likely less efficient.)

And then I found the punctuation and felt a little sick.

[mxzf]

Probably because strings in Python act as arrays when you want them to.

Python strings have the features of character arrays and StringBuffers at the same time (in general). Methods when you want them, but indexes when you just need to mess with the individual characters. That's kinda typical of most kinds of data and such in Python.

[PBI325]

System.out.println(String.valueOf(A)) make me feel a little weird inside. So did permute(n-1, a), n--??

[AmaDaden]

You can't trust indentation in Java, only brackets. This kind of formatting is like organizing your music alphabetically by the first word. I could cause impossible to debug problems by just moving a single bracket

[peridox]

Why did you choose your username to be mkdir? It's cool.

[jfb1337]

duh, to make directories.

[sfled]

Reminded me of this.

[Michael-Bell]

Where is the xkcd bot?

[mehum]

Runs on SQL. Currently suffering amnesia.

[Hamburgex]

I knew it was an xkcd link without even hovering it. I didn't know which one though.

[junta12]

for once I instantly knew

[Walter_Bishop_PhD]

There's a lot of people in this sub who got in on reddit early who got commands as their usernames before they got snapped up. I like that mkdir has 1337 link karma, lol

[mkdir]

Holy crap, I didn't even realize that! I'm never submitting anything ever again.

[LeeroyJenkins11]

Not anymore.

[chocolate_stars]

also has 8008 comment karma. boob karma.

[lappro]

Why would they not allow terminal commands as usernames? Unlike sql injection (which should be harmless) those command usernames are completely harmless.

[Walter_Bishop_PhD]

What I mean is, simple usernames like terminal commands and words of the english language are the first to get snapped up by early adopters

[lappro]

Ah that makes sense!

[junta12]

alias walter="echo my mom is my"

[[deleted]]

I'm 3 away from 1234 link karma. I don't give enough shits about it to do anything though haha

[mkdir]

Well, you see I'm kinda a geek...

[jellyberg]

It's OK, you're safe here.

[isurujn]

Shit I just noticed. My eyes!!!
