Unlimited Args as Param

[Prince Pwn]

Why does the following code work in Netbeans and not in RTP. Only difference I know is RTP uses Java 1.4.x and Netbeans uses a later Java version. When I F2 indent in RTP, the dots in the param and colin in the for mis-allign.

Java:

public static void main(String[] args) {         System.out.println(average(10,40,50));     }      public static double average (double... numbers)         {             double total = 0;             for (double d: numbers)                 total += d;             total /= numbers.length;             return total;         }

Variable-length parameters were introduced in verson 1.5 (aka Java 5). Stop using RTP, its a waste of time.

Name one other IDE that compiles and executes on the fly, auto-indentation, syntax highlighting and I'm sold. NetBeans = slow, JCreator = slow, Notepad & cmd = slow.

RTP is version locked (stuck on 1.4 permanently) while other IDEs are just that, IDEs. Developing environments that update with the language (in fact, you can update the language without changing the IDE at all).

This is an outright lie. The command line is damn fast, faster in fact than any IDE. IDEs have GUIs bogging them down and do exactly the same thing, but invisibly or with restricted compiler output. I compile everything from the command line, because it's faster and because it makes me look 1337. Hell, my IDE is just a text editor with syntax highlighting.

Eclipse.

you can always make a batch file or just make a java program that compiles and runs it for you. Then notepad won't be so bad. I personally prefer netbeans, except it's more like project based =(

I think they probably meant in terms of actually setting it up to compile, not compile times. Also generally not true, but it makes a bit more sense.

OT, I'd also recommend Eclipse. It's the best I've used so far.

I admit, it's a bitch to get the command line working the first time on Windows, but once you've figured it out it's very quick to update or add compilers and interpreters.

OS X has them in developer tools. One install comes with Ruby, Python, Java, C++ and more compilers and interpreters. The actual usage, depending on how you've formatted the file, is 'ruby myfile' or 'g++ myfile' If you adjust the permissions you can run the file with a double-click (I dunno if this works for compiled languages, you prolly need a binary).

[chrisbrown]

Unless I'm misinterpreting, if you're using g++ in that way, then it does indeed work with compiled languages.

I've done that

You still type your code, ctrl+s, alt+tab, inside cmd do UP ARROW then hit return and even then it takes 1 second + to compile on a quad, then finally you alt+tab back to your code.
Whereas F1 executes and compiles on the fly on the same system. No clue why but using an IDE somehow compiles faster than the cmd!
