non-static variable cannot be referenced from a static context

[keo]

I tried googling, but still can't figure this out:

I've got a GUI class and another class.

I want to say when a radio button is selected in the gui class, it changes a variable.

-variable-

private int variable = 0;

-1 of the button method bodys-

~~button header~~
variable = 2;

-getMethod-

public int getVariable() {
   return variable;
}

And in the other class:

public int getVariableHere(){
   int i = classGUI.getVariable();
   return i;
}

The Error appears on the line int i = classGUI.getVariable();

Are you calling the getVariable method on the class or on an object of the class? You probably should be doing the latter.

getVariable() is getting this: private int variable = 0;

[Fubarable]

getVariable() is getting this: private int variable = 0;

No, you don't understand. You are calling this method on this: classGUI

and this appears to be a class, not an object of a class and that's not allowed. The solution is to create a classGUI object and call the method on that object.

THANK YOU! It has compiled now.

Good, I'm glad it compiles. Now you'll have to make sure that you are calling this method on the right object. Sometimes you don't want to create a new object for this, but rather have the correct object passed into your class so that you can act on it.
