There are several ways to add action to the JButton, perhaps the simplest one is by anonymous class:

    b1.addActionListener(new ActionListener() {

        @Override
        public void actionPerformed(ActionEvent evt) {
            //evento aqui
        }
    });

This form is often used when nothing is too complex in the action. If you're using 8, things get a lot easier:

b1.addActionListener(e -> {
            //ação aqui
        });

The easiest way is this: You add the action to Button:

b1.addActionListener(this);

Then you'll create this action:

public void actionPerformed(ActionEvent e) {
        //O código que queiras
}

But for this to be possible, you have to implement a ActionListener :

public class NOME_DA_CLASSE implements ActionListener{
    //Código    
}
