What should I do with jButtonActionPerformed() ,si that when button is clicked then it will open a new window(new frame)?

Question

Please help me via giving some lines of code

Answer 1

public class Main extends JFrame implements ActionListener{
public Main(){
JPanel panel = new JPanel();
JButton testbutton = new JButton("Click Me");
panel.add(testbutton);
testbutton.setBounds(5,5,80,30);
testbutton.addActionListener(this);
public void actionPerformed(ActionEvent e){
Object source = e.getSource();

if(source==testbutton){
JFrame frame2 = new JFrame();

}
}
}
public static void main(String[] args){
JFrame frame = new Main();
frame.setSize(300,300);
frame.setLocationRelativeTo(null);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setResizable(false);
frame.setVisible(true);
}
}
There can be errors here since I dont have my laptop right now. It's up to you to find those. I hope it helps 😉
