Main(String [] args)

[Ray Dawson]

Say I have a code with main(String[]args) and I want a recursive function, then how should I go about it ?

Like without String[]args, here's what I do

public class HelloWorld
{
public static void main()
{
System.out.println("Hello World");
callback();
}
public void callback()
{
main();
}
}

It goes on infitenely calling main over & over again.

So I want to do this while having String[]args as parameters in the main().

How do I do this ?

Like this:

public static void main(String args[]) {
	main(new String[]{});
}

Or just "main(args)". That's an example of "direct recursion".

If you have two methods that call one another -like in your example-, that's called "indirect recursion".

It worked :jumpingjoy:

And don't try mixing static and instance methods like that. The compiler won't like it.

Yeah that's one thing which I did try to avoid.

In my main program, I have about 5000 lines of code, with say about 30 functions. All are static & all variables are public & static.
I'm working on multiple threads right now, so you think having public static everywhere can make them thread-unsafe ?

Then you should step away from the keyboard and go find yourself another language... ;)

You are not really doing it in an object oriented way. Normally, I allow main-containing classes to be about 3-14 lines. The rest should be taken care of by other instances of other classes.

If you are doing functional programming, there are several suitable languages, eg Oz, Prolog, LISP, ML. But not Java™.
