How to create a window with two buttons that open a new window

Question

I need a program - the main JFrame has 2 buttons

• Button
• button2

When I click the button, it should open a new JFrame window with new parameters, and if I click 2, open another window.

In these two new windows, I have to add buttons such as the next and previous.

I have a problem when I open button 1, then 2 windows open and the main JFrame is still visible.

My first swing program:

import javax.swing.*; import java.awt.*; import java.awt.event.*; public class example { public static void main (String[] args){ JFrame frame = new JFrame("Test"); frame.setVisible(true); frame.setSize(500,200); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel panel = new JPanel(); frame.add(panel); JButton button = new JButton("hello agin1"); panel.add(button); button.addActionListener (new Action1()); JButton button2 = new JButton("hello agin2"); panel.add(button2); button.addActionListener (new Action2()); } static class Action1 implements ActionListener { public void actionPerformed (ActionEvent e) { JFrame frame2 = new JFrame("Clicked"); frame2.setVisible(true); frame2.setSize(200,200); JLabel label = new JLabel("you clicked me"); JPanel panel = new JPanel(); frame2.add(panel); panel.add(label); } } static class Action2 implements ActionListener { public void actionPerformed (ActionEvent e) { JFrame frame3 = new JFrame("OKNO 3"); frame3.setVisible(true); frame3.setSize(200,200); JLabel label = new JLabel("kliknales"); JPanel panel = new JPanel(); frame3.add(panel); panel.add(label); } } } 

Answer 1

You add your ActionListener twice to the button . So return the code for button2 to

  JButton button2 = new JButton("hello agin2"); panel.add(button2); button2.addActionListener (new Action2());//note the button2 here instead of button 

Also, perform Swing operations in the correct thread using EventQueue.invokeLater
