Answer 1

It's really simple.

I suppose you have an instance of your button, right? Let's say that instance is called myButton.

You can just add an action listener by calling addActionListener:

myButton.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {
        // Do whatever you like here
    }
});

Protip: next time you don't know what method to call, just type the instance name and .. Then, your IDE will show you all the methods you can call, unless you are not using an IDE. If that is the case, download one.
