In this example we are going to see how to use JTextField Action Listener.
Java Code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | import java.awt.event.ActionEvent; import javax.swing.JFrame; import javax.swing.JTextField; public class Main { public static void main(String[] a) { JFrame frame = new JFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JTextField jTextField1 = new JTextField(); jTextField1.setText("jTextField1"); jTextField1.addActionListener(new java.awt.event.ActionListener() { public void actionPerformed(ActionEvent e) { System.out.println("action"); } }); frame.add(jTextField1); frame.setSize(300, 200); frame.setVisible(true); } } |
Output:
1 2 3 4 | action action |
