Java – how to put hover effect on JButton?

I'm trying to create a java desktop application. I use two buttons I want to add a hover effect to these buttons I think: when I click any button, it should change its background color

How can I achieve it?

This is my code:

public class Party1Party2 extends JFrame
{
    JButton b1;
    JButton b2;
    Container pane;

    public Party1Party2()
    {
        getContentPane().setBackground(new java.awt.Color(255,255,255));

    b2.addActionListener(new ActionListener()
    {
        public void actionPerformed(ActionEvent ae)
        {
            JOptionPane.showMessageDialog(frame,"Welcome to allhabad High Court");
        }
    });

    b1.addActionListener(new ActionListener()
    {
        public void actionPerformed(ActionEvent ae)
        {
            JOptionPane.showMessageDialog(frame,"Welcome to allhabad High Court");

        }
    });
  }
}

Solution

You can use the mouse to enter and exit JButton and do whatever you want

For example:

jButton1.addMouseListener(new java.awt.event.MouseAdapter() {
    public void mouseEntered(java.awt.event.MouseEvent evt) {
        jButton1.setBackground(Color.GREEN);
    }

    public void mouseExited(java.awt.event.MouseEvent evt) {
        jButton1.setBackground(UIManager.getColor("control"));
    }
});
