How to close a GUI on JButton click

Question

I have written some coding that has a GUI that has an enter button that, when clicked, opens the tool that I have created, but what I also want the jbutton to do is to close the first GUI down as well as open the tool I have created, I have tried changing the setVisible(true/false); statements but they just hide the GUI's and it doesnt run.

So to sum up, I want my JButton to have two functionalities, one to close the current GUI and one to open the tool I have created.

I think it has something to do with this coding to make the enterButton close the GUI:

public void actionPerformed(ActionEvent e){ 
    if(e.getSource() == enterButton){
        // coding to make the GUI exit???
    }
}

Why use 2 GUIs rather than a `CardLayout` or similar? See [The Use of Multiple JFrames, Good/Bad Practice?](http://stackoverflow.com/a/9554657/418556) for more details. — Andrew Thompson, Feb 22 '13 at 16:09

You can use System.exit(0) like this :

public void actionPerformed(ActionEvent e){ 
    if(e.getSource() == enterButton){

        //coding to make the GUI exit???

        System.exit(0); 
    }
}

or use dispose()

public void actionPerformed(ActionEvent e){ 
    if(e.getSource() == enterButton){
        //coding to make the GUI exit???

        this.dispose();
    }
}

The first suggestion would only work if the 2nd GUI was started in a separate `Process`. The 2nd suggestion might work if the 1st frame sets `DISPOSE_ON_CLOSE`. – Andrew Thompson Feb 22 '13 at 16:11
yeah, the first suggestion closes the whole thing down including the 2nd GUI – tom bannister Feb 22 '13 at 16:21
