Replacing Containers?

[IndiDev]

Hello Community,

I'm developing a little game and i got stuck at the part where im trying to replace the content of the start menue with the content of the options menue. I don't want it to open a new Window after clicking the "Options"-Button in the Start menue. I tried to replace the container of the start menue with the container of the Options class by using getters but it won't work. I shortened the program for purpose of questioning.





//Listener Class of the menue class

import java.awt.event.*;
import java.awt.*;
import javax.swing.*;

public class MenueListener implements ActionListener{
Menue m;
Options o;

public MenueListener(Menue me, Options op){
m = me;
o = op;
}
public void actionPerformed(ActionEvent ae){
Object ob = ae.getSource();
for ( int j = 0;j< 3;j++){
if (ob.equals(m.getBtnOp(j))){
switch(j){

//start game button
case 0: Game g = new Game();

break;

//options button
case 1: //before trying the container replacing i tried to make every single element invisible
// and add new stuff to the container, but then i thought there must be an easier way, so i tried container replacing.
/*m.getL1().setVisible(false);
for (int k = 0;k < 3;k++){
m.getBtnOp(k).setVisible(false);
}
JLabel l2 = new JLabel(new ImageIcon("OptF.png"));
l2.setBounds(0,0,515,555);
m.getC().add(l2);
l2.setVisible(true); */

o.getC.add(m.getL1());
break;

//end game button
case 2: System.exit(0);
break;
}
}
}
}
}

I came up with this idea when i looked at the constructor of my menu where i wrote
c.add(l1);
to add the whole stuff of JLabel l1 to my Container c
so i tried to replace the variables in the Listener like this
o.getC.add(m.getL1());
But I get this error while compiling the program.
MenueListener.java:31:41: error: cannot find symbol
o.getC.add(m.getL1());
^
symbol: variable getC
location: variable o of type Optionen



I would be a big help if someone could give me a hint or another idea of replacing Frame content by button clicking.

Sounds like a job for CardLayout.
