We would like to know how to add click event handler pre JDK 8 to JButton.
/*from w w w . j av a2 s . c o m*/ import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JButton; import javax.swing.JOptionPane; public class Main { public static void main(final String args[]) { JButton button = new JButton("Test"); button.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { System.out.println("Button pressed"); } }); JOptionPane.showMessageDialog(null, button); } }
