import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JFrame;
public class Demo {
public static void main(String[] args) {
Demo demo = new Demo();
demo.run();
}
public void run() {
JFrame frame = new JFrame("title1");
frame.setLayout(null);
frame.setBounds(10, 10, 500, 300);
Button button = new Button("click");
button.setBounds(15, 15, 200, 100);
frame.add(button);
frame.setVisible(true);
button.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
JFrame frame = new JFrame("title2");
frame.setLayout(null);
frame.setBounds(20, 20, 300, 100);
frame.setVisible(true);
}
});
}
}
