How to make int variable visible to other class from GUI JButton

Question

I'm trying to access the int myInt in this GUI form class from another class. The method does pass the input variable to myInt properly but I have not been able to make it visible to the other java file. I have been reading about scope and class declarations and have been able to muddle along up until now, but I am doing something wrong here. Nothing I have tried has worked.

            String[] row = {key, value};
            aboutModel.addRow(row);
        }
    }   
}

Answer 1

myInt should be declared inside the class, but outside of any method implementations:

public class AllocationDialog extends JDialog {

    public int myInt;

    // ...
}
