I already tried making a popup menu, but i don't want a menu, i want a window, and i can't seen to find out how to do it :( It's probably easy, but i don't have enough knowledge in java

Ok so,for this you will need 2 JFrames. First one is where the buttons and everything is and the second one is the one that will popup. You will have 3 classes: Main, classWhere1stJframeis, ClassWhere2ndJframeis.
好的，为此您将需要 2 个 JFrame。第一个是按钮和所有东西所在的位置，第二个是将弹出的那个。您将拥有 3 个类：Main, classWhere1stJframeis, ClassWhere2ndJframeis。
This is main:
这是main：
package proba;
import javax.swing.JFrame;
public class mejn {
public static void main(String[] args) {
// TODO Auto-generated method stub
Frame1 frejm = new Frame1();
frejm.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frejm.setVisible(true);
frejm.setSize(250, 300);
}
}
This is Frame1:
这是Frame1：
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
public class Frame1 extends JFrame {
JFrame Frame = new JFrame();
JButton Button1 = new JButton();
public Frame1()
{
super("The title");
Frame = new JFrame();
Button1 = new JButton();
Frame.add(Button1);
thehandler handler = new thehandler();
Button1.addActionListener(handler);
}
private class thehandler implements ActionListener
{
public void actionPerformed(ActionEvent event)
{
if(event.getSource()==Button1)
{
Frejm2 frejm = new Frejm2();
frejm.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frejm.setVisible(true);
}
}
}
}
This is Frame2:
这是Frame2：
import javax.swing.JFrame;
public class Frejm2 extends JFrame {
JFrame Frame2 = new JFrame();
public Frejm2()
{
super("Title");
}
}

that is not just a panel you want to pop up that would be considered a whole other frame. I would suggest making a different JFrame class that when the button is clicked instantiates the other frame.
这不仅仅是您想要弹出的面板，它会被视为整个其他框架。我建议创建一个不同的 JFrame 类，当单击按钮时实例化另一个框架。
