for loops

[kateryan13]

A for loop is usually written as
for(i =0; i<10; i++)
However, instead of i++ I want to go up in increments of 20000, and my program wont compile when I write i + 20000, does anyone know how you do this??
Thanks very much!

Try using i+=20000.

I haven't used this in Java, but it is valid in C. In C, you can use any valid expression to alter the value of i. I would think that the same is true in Java.

In your example i + 20000 doesn't change i whereas i+=20000 or i = i + 20000 do.

public class ForCounter 
{ 
    public static void main(final String[] args) 
    { 
        for (int i = 0; i < 1000000; i++) 
        {
            i+=20000;
            System.out.println(i); 
        } 
    } 
} 

Like this? There's a problem. It keeps summing "i" every iteration by 1.

Hrmm..

Kind regards,

Nar, like this:

public class ForCounter 
{ 
    public static void main(final String[] args) 
    { 
        for (int i = 0; i < 1000000; i+=20000) 
            System.out.println(i); 
    } 
}

Regards.

lol, that's weird. I swear, I compiled it like that too and it gave me an error. :|

Hmm... Thanks for the quick reply. I learned something as well as the guy who asked the original question!
