Help with public variables

Hey, I thought I could make a public variable and then have multiple lower level functions modify this variable. Is that not correct? What am I doing wrong, any help would be greatly appreciated. Thanks!



public class testapp extends Applet implements MouseListener {


*declare a bunch of public arrays*


public void math() {


*do a bunch of math*

}


public void map(graphics){

*graphics*

}}

at the end it just outputs 0 for all those variables.

are those functions even working?

Its kinda hard to say, but I dont see the functions math(), or map() called from anywhere, so the integer variables could simply be outputting their defualt 0 value

...Try to use code tags when you post code.

Ya, I was playing around with that.

public void main(Graphics g){

math(g);
map(g);

}

I am not sure that is working though

Thanks

The mapping function is certainly working... its outputting the right variables in the right places, all the variables are simply 0.

Either the math function isnt running or the variables are not being passed back and forth properly. Help!

try doing this:

Code:

---

public class testapp extends Applet implements MouseListener {
        *declare a bunch of public arrays*

        public void start() {
                math();
                map();
        }

        public void math() {
                *do a bunch of math*
        }
        public void map(graphics g){
                *graphics*
        }
}

---

It worked! Map runs without the start thing, but math does not.

Thanks!

No problem, You're the first i've helped on this forum!
