A procedure is just a function that doesn't return any value, so why not do that in Java? A function in Java is a method btw.

I am new to java so this might be a little bad code but feel free to correct me


code:
//A procedure that outputs something.
public static void myProc {
System.out.println("Something");
}


Now...

code:
//A function that returns an "int" product of 2 ints.
public static int Multiply (int a, int b) {
return a * b;
}

You've got the basics. However, all method names should begin with a lower-case letter.

Also, use the Java syntax highlighting. Smile

code:
[syntax="java"][/syntax]


Oh, and please indent, and don't leave spaces between the parameter list and the method name.

I'm not liking these Java conventions...

that's not just a java convention.. it's a C/C++/Perl/and quite a few other langs that support a C-like syntax.. convention... get used to it.. it's the way the world works..

Amen to that.

And yes, there are procedures in java, like turing, but the Java program is strictly Object-Orientated. EVERYTHING is an object. Turing is a procedural language . . . things are done in procedures. So your program is an "object" and the object has methods (procedures/functions), and fields (variables). The methods belong to the object. The object can use the methods, or if the methods are public other objects can either create an instance (like taking a blueprint and making something new) and use it's function (if it's non-static) or it can call on the object's method through referencing through the object, like this: MyObject.myMethod(); These methods are "static" methods, meaning they're attached to their class. I hope I'm right. rizzix/wtd, Please correct Smile

Hmm... Maybe I could just ignore it altogether? Laughing

I just don't understand it. Having spacing between the brackets, spacing after the method name, and a whole bunch of other stuff makes the code so much more readable. We need more whitespace! Smile

Ah, it doesn't matter either way. If it's so important I will learn it some time, right now I am mostly programming 'for fun'.

More or less right, though as I specify in the Introduction to Java thread in Java Tutorials, perhaps a better term is "context".

See "A bit of theory" and "Creating your own methods".

alright. I think i got it. so i use..
code:

//A procedure that outputs something.
public static void myProc {
System.out.println("Something");
}

to make the procedure. but how do you play or run the procedure?
and yes i can't spell and yes i am lazy
