Adding action listeners to JButton

Posted by Hiran on January 25, 2002 at 10:45 AM

How do I add an action listener to JButton? I've done this before, but I must be doing something wrong, because I'm getting an error message. Here's my code:

public class HoursTrackerGUI extends JFrame
{
	private JButton setStartTime = new JButton("Clock in");
	
	public HoursTrackerGUI()
	{
		super();
		this.setSize(400, 300);
		
		Container contents = this.getContentPane();
		contents.setLayout(new FlowLayout());
		contents.add(setStartTime);
		
		setStartTime.addActionListener(new SSTListener());
	}
	private class SSTListener implements ActionListener
	{
		public void actionPerformed(ActionEvent e)
		{
			System.out.println("The button was pressed!");
		}
	}
}

              • You don't need to import the package where you place your class. Kishori Sharan January 25, 2002 at 5:10 PM (0)
