Java – how to reference the object that created the object?

In Java, I have an object to create a button In the onclicklistener of the button, I want to reference the object that created the button

Is there any simple way to do this?

Solution

It depends on how you build it Typically, instances have no reference to the instance that created them unless you pass them in and store them somewhere But if you do this:

public class YourClass {
    public void foo() {
        JButton b = new JButton();
        b.addActionListener(new ActionListener() {
            @Override public void actionPerformed(ActionEvent e) {
                // Need reference to YourClass here
            }
        });
    }
}

Then you can use yourclass This to reference the external yourclass
