如何破坏前一帧打开一个新的框架

Question

I am building an application in java that has 2 JFrames. 1st frame has a button that upon clicking should open the next JFrame while the previous one should close. I know how to display the next frame but: How do I close the previous JFrame automatically when the next JFrame opens ?

I tried thie following code:

addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent arg0) {
                new GUI();//next frame
                                this.dispose();//compile-time-error
            }

Answer 1

Where you call this.dispose() , the object referred by this is an instance of ActionListener . To invoke the instance of GUI type GUI.this.dispose() instead.
