I have a class in which I have declared a boolean value, like so.

Class1:

public static boolean GLOBAL_PVP = false;

And in this class, I have created a method to return the boolean. I have done this so that I can import Class1 into Class2, and have Class2 read the boolean's value.

Class1:

public static boolean GLOBAL_PVP = false;

public static boolean GlobalPvp () {return GLOBAL_PVP;}

I read some material on stackoverflow that seemed to suggest this was a poor way of handling booleans, but I don't know how else to do it.

I can then access the boolean GLOBAL_PVP from Class2 like so:

Class2:

if (Class1.GlobalPvp()) {
    return true;
}

(this is inside yet another boolean that determines if combat is possible or not. I wish to be able to override this check if global PvP is enabled, and thus, GLOBAL_PVP is true.)

***

Here's where I'm stuck. I can get the value just fine. But how do I set the value of GLOBAL_PVP from Class2?

Thanks for any light you can shed, I'm very new at Java.

It really just depends on what you're trying to do.

Since your variable is public, you don't even need get/set methods. You can just do

Class1.GLOBAL_PVP = true;

To set it, and you can just access it the same way, i.e.:

if(Class1.GLOBAL_PVP)

But like Stack Overflow, this is sort of a shitty way of doing things.

why would u need to make it global?
make the method in Class2 accept a Class1 object, then you can use getter/setter methods of Class1 on the object. Or inherit Class1 if appropriate, not sure whats the exact situation.

I would recommend using getters and setters.

Example below.

public class A {
   
    private static boolean exampleVar = false;

    public static boolean getExampleVar() {
        return exampleVar;
    }

    public static void setExampleVar(boolean exampleVar) {
        A.exampleVar = exampleVar;
    }

}



public class B {
   
    public static void main(String[] args) {
        System.out.println(A.getExampleVar()); //prints out false
        A.setExampleVar(true);
        System.out.println(A.getExampleVar()); //prints out true
    }

}

        System.out.println(A.getExampleVar()); //prints out true
    }

}

Oh, thanks guys. Kinda forgot about this thread, I never subscribed to it :fp:

hadesflames walked me through the logic of his example through Skype, I've since then set up many booleans that can be toggled cross-class.

I will probably revamp them in the future to use getter and setter methods, as I see those everywhere and they seem like a very elegant way to do things.

Thanks again!
