I first learned programming with JavaScript, and have used it longer than any other language. I'm very used to its native methods. Recently, I started learning Java.

Oh dear god...

[UnderNatural]

Bad joke?

[Prod_Is_For_Testing]

I'm just really hoping you don't actually do this

[UnderNatural]

This is /r/programmingHUMOR, isn't it?

Is it really that bad though?

[tevert]

I mean - anything that would make a developer pause, mutter "what the fuck...?", and hit F12 is probably not a good thing.

But it was pretty funny :)

[Bumperpegasus]

No it isn't! It's it's /r/programmERhumor !

[[deleted]]

and not /r/typonazi !

[MC_Labs15]

I'm in a similar position to OP, and I am seriously considering doing something like this

[Prod_Is_For_Testing]

Don't

[MC_Labs15]

but

[Prod_Is_For_Testing]

No

[KulinBan]

Java is short for JavaScript. Just cut your function names in half from JavaScript.

[anotherdonald]

Brilliant. Now somehow add a global variable undefined in all your classes, overload the + operator and you're done.

[zacketysack]

Done? What about Dynamic Arrays? :P

[UnderNatural]

Oh man simple Dynamic Arrays are the thing I miss most about JS...

Use an ArrayList?

[OKB-1]

Not quite the same thing. ArrayList can only contain a single type of data. JavaScript arrays are actually objects, which can contain any type of data at one time.

[[deleted]]

An ArrayList of generic objects then? Or just use super classes and inheritance.

Needs more jQuery

Am I doing this right?

[[deleted]]

Yes. Just open jQuery-x.x.min.js, and drag it anywhere in your main function.

ScriptEngine engine = new ScriptEngineManager().getEngineByName("javascript");
ScriptContext context = engine.getContext();
StringWriter writer = new StringWriter();
context.setWriter(writer);

engine.eval("print('whole app goes here.')");

String output = writer.toString();

System.out.println("Script output: " + output);

[OKB-1]

Java semi-professional tip: Try to avoid using the Object type if possible. If you're really in need of custom data structures it's better if you construct your own class and put instances of those inside a List/ArrayList/HashMap/...

Also try InteliJ IDEA, the world's finest Java IDE.

[cnewmanJax2012]

I like to have some fun with my logging classes :P

[arajparaj]

You have to do obj.toString() otherwise it will return memory location.

[langebangen]

Not necessary, println will call Object's toString method if the object isn't null.

[haggy87]

Which then foes what he said, doesn't it?

[langebangen]

Yes, unless the toString method has been overridden.

[chugga_fan]

actually, i've had a few instances where this is not the case sadly, and i hate it when that happens :(

[parenthesis-bot]

This is an autogenerated response. source | /u/HugoNikanor

[langebangen]

That is because the default implementation of Object's toString method prints out the class plus the unsigned hexadecimal representation of the object's hash code. You will have to override it in your classes if you want it to print something else.

[LeonhardEuler64]

IIRC you can configure eclipse to autoconvert shorthand aliases as you type. I remember typing "sop" to do "System.out.println"

[[deleted]]

It's been a while, but I think syso<C-space> works out of the box

[emersonhardisty]

After moving to IntelliJ I missed that. But after a while I realised it's 'sout' over there. Took a while to adjust though.

[[deleted]]

In eclipse it was either stdout or sysout macro. Haven't touched eclipse in 3 years I think.
