Try this: // ChangeFrameName.java import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JButton; import javax.swing.JFrame; public class ChangeFrameName { private static JFrame frame; private static void createAndShowGUI() { frame = new JFrame(Original name); frame.setSize(300 300); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JButton button = new JButton(Change Name); //Add action listener to button button.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { if(frame.getTitle() == Original name) { frame.setTitle(New name); } else { frame.setTitle(Original name); } } }); frame.getContentPane().add(button); frame.setVisible(true); } public static void main(String[] args) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { createAndShowGUI(); } }); } }
