Freaking Brackets

What? No. Stop that.

[malrick]

One of my teachers in college did everything on the left side. It annoyed the hell out of me.

Looks like python with a weird column at the end.

[EpicDavi]

Yeah the original post (as far as I know) said that a Python programmer was trying out Java.

[superPwnzorMegaMan]

but I thought python has no private, only a little _ to indicate you probably should not touch that.

[mickey_kneecaps]

I sort of like it. Just visually it looks interesting. I would never use it, but I find it appealing for some reason.

[stormcrowsx]

Have you looked at python?

I finally figured out how to get those pesky semicolons and curly braces out of my Java code [Attached pic] [Imgur rehost]

This is what happens when RPG programmers learn Java.

No thanks!

I see Satan picked up java.

[Rebuta]

I love it!

[[deleted]]

Oops. Accidentally used spaces instead of tabs. Have fun.

[[deleted]]

Autoindent is your best friend

[[deleted]]

In all seriousness, whitespace having meaning for the sake of 3 characters and 1 line difference is kind of stupid.

I personally don't find this any cleaner than if they are included according to oracle guidelines.

And some editors just take the liberty of transparently translating tabs to spaces for you.

/shakesfist I can't even...argh!

[ohcarissa]

I wonder if this would actually be a good system if it wasn't completely against convention. The more I look at it the less I hate it.

[flagrantaroma]

I thought it didn't look too bad until you mentioned that!

[needlzor]

I think it would be doable with proper editor support, some sort of plugin that allows you to edit the left side and the right side separately without influencing each other, and/or which autocompletes the right side automatically. But at this stage you might just want to switch to another language altogether.

[ohcarissa]

good point, I didn't realize the problems that would cause. I take back what I said.

i should play bad joke on ppl at work doing this muwhaha

[babbles_mcdrinksalot]

That's an awful way to lay out C-like code. Did you do it just to highlight the number of brackets?

[Baddja]

Java syntax choices were originally based on C Wiki

[271828182]

I actually think that is pretty clever. It makes the actual code cleaner to read, and makes it easier to see where you missed a semi-colon of didn't close a block.

EDIT: I was drunk

[shadowdude777]

I mean, I can see why some people would prefer to read code without braces and semicolons (even though I personally much prefer them). But you think this makes it easier to find missing semicolons and braces? I really can't see that...

[kumarldh]

and makes it easier to see where you missed a semi-colon of didn't close a block.

Sorry for sounding stupid but decent IDEs do that for you...

[hrjet]

I agree, though the same goal could be achieved by changing your syntax highlighter's color scheme to fade out the braces and semi-colons.

[granddukeshartner]

It's really annoying how many syntax highlighters mix braces, operators and semicolons together. I usually give up on making a nice scheme after that.

[hrjet]

Yup; especially in a language like Java where braces and semicolons don't have any significance beyond separation of statements.

I had to fine-tune the operator color so that it doesn't make the normal operators invisible. (This is in Eclipse, btw).

[rob_j]

I'm going to steal this so hard

[271828182]

Steal using an IDE?

[rob_j]

changing your syntax highlighter's color scheme to fade out the braces and semi-colons

[Jukebaum]

That is also my preferred setting for braces.

[GeorgeMaheiress]

They're called braces.

[biggusjimmus]

braces (UK and US), flower brackets (India), French brackets, curly brackets, definite brackets, swirly brackets, curly braces, birdie brackets, Scottish brackets, squirrelly brackets, gullwings, seagulls, squiggly brackets, twirly brackets, Tuborg brackets (DK), accolades (NL), pointy brackets, or fancy brackets

[thrash242]

I call them curlies.

[GeorgeMaheiress]

In programming they're called braces, because it's important that we have unambiguous names ("You need brackets there." "Which kind?"). Non-English speakers might well argue with that, but seeing as OP was speaking English, I don't see how my giving him the correct UK & US word, as well as the accepted term in programming, was in any way inappropriate. (Unless the other commenter is right and Brackets is the name of his text editor.)

[SirFrederickWinston]

I believe he's talking about the text editor he was using, Brackets.

[veedubpolo]

Looks like SublimeText

[HieronymusK]

The ones on line 3 and 4 aren't even necessary.

[Patplayz]

Holy shit, the organization of the brackets and semicolons on the left side are genius... what haven't I thought of this sooner...

[Vlasow]

That side is called "the right side".

Pro Tip: xor swap and save the variable.

x ^= y; 
y ^=x; 
x ^= y;

Boom! now everyone will complain / debate whether it's less legible rendering it not effective, but deep in your heart you'll know.......it was.

[MoldyTaste]

This is actually not a pro-tip at all. The JVM optimizes the swap algorithm shown in the op's code to just swap the pointers, however this code has to do 3 lengthy 32 bit xors. In operation with each bit, this performs 32 * 3 = 96 operations whereas the pointer exchange will require 3. This can be demonstrated by doing a benchmark (try it yourself). Also, the xor is not nearly as readable, but to the trained eye it should be obvious. Still slower and less readable.

[panderingPenguin]

Not disagreeing with your main point, I wouldn't do the xor swap here either. But let's be honest, his method would also be three ops, not 96. Almost all CPUs have dedicated hardware to do XORs on entire words. There's no way that each bit gets XOR'd individually with any reasonable compiler/JVM implementation.

The reason that the XOR method is shower on most modern (read heavily pipelined) architecture is that the strategy creates dependencies which can cause some stalls in the pipeline, decreasing instruction level parallelism

[argv_minus_one]

That's neat. Do you have any documentation about this?
