Question

As the title says, I’m trying to do something like this:

public abstract class ClassA{

    private String var;

    ...


    protected void setVar(String var){
        this.var = var
    };

    protected String getVar(){
        return this.var
    };  
}

public class ClassB extends ClassA{

    public ClassB(...){

        object.setListener(new Listener(){
            @Override
            public void onItemSelected(data ...){
                // Would like to do:
                var = data;
                // BUT:
                // CANT CALL VAR since its a private String of Class A
                // CANT CALL setVar(data) since it will end up looping
                // CANT CALL super.setVar(data) since super dosn't point to ClassA in here
            };
        });
    }

    @Override
    protected void setVar(String var){
        super.setVar(var);

        // DO MORE STUFF WHICH WILL CALL THE LISTENER
    };
}

Sure, I could make var public, but that’s not what I want! var should remain protected, changes should only happen using the setters.

Is there a way?

Try this:

object.setListener(new Listener(){
public void onItemSelected(data ...){
    ClassB.this.var = data;
}});
