Newbie: ActionListener visibility problem

Question

Hello,
i'm new to java, and i'm working on a simple small project.
I've got a problem with the visability of an object.
Maybe you have a look at my code:
Used Class
public class System1T1P extends xyz {
public void switchOn() {
// Important READ HERE
// Important READ HERE
// Important READ HERE
System.out.print("old"); // for debug
// Important READ HERE
// Important READ HERE
// Important READ HERE
public void start() {
public void update() {
// has to be implementated
class TimerListener implements ActionListener {
        public void actionPerformed(ActionEvent e) {
             update();
Timer oTimer = new javax.swing.Timer(1000, new TimerListener());
}Main Class
public class GUI_1T1P extends GUI_General {
     // System
     private System1T1P oSys1T1P = new System1T1P() {
          public void update() {
          public void switchOn() {
               // Important READ HERE
               // Important READ HERE
               // Important READ HERE
               System.out.print("mimi"); // for debug it returns something else
               // Important READ HERE
               // Important READ HERE
               // Important READ HERE
     // Screen Size
     GraphicsEnvironment oGraphicsEnvironment = GraphicsEnvironment.getLocalGraphicsEnvironment();
     Rectangle oRectangle_ScreenSize = oGraphicsEnvironment.getMaximumWindowBounds();
     // Gui
     JFrame oJFrame;
     JButton oJButton_exit;
     JButton oJButton_on;
     JButton oJButton_running;
     GC_1T1P oGC_1T1P;
     public GUI_1T1P() {
          // Important READ HERE
          // Important READ HERE
          // Important READ HERE
          oSys1T1P.switchOn(); // Returns "mimi" to out
          // Important READ HERE
          // Important READ HERE
          // Important READ HERE
          oJFrame = new JFrame("System 1T1P");
          oJFrame.getContentPane().setLayout(null);
          oJFrame.addWindowListener(new WindowListener() {
               public void windowClosed(WindowEvent arg0) {}
               public void windowActivated(WindowEvent e) {}
               public void windowClosing(WindowEvent e) {
                    System.exit(0);
               public void windowDeactivated(WindowEvent e) {}
               public void windowDeiconified(WindowEvent e) {}
               public void windowIconified(WindowEvent e) {}
               public void windowOpened(WindowEvent e) {}
          oJButton_exit = new JButton("Hide");
          oJButton_exit.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent arg0) {
                    hide(); // works without problems
          oJButton_on = new JButton("Activate");
          oJButton_on.addActionListener( new ActionListener() {
               public void actionPerformed(ActionEvent arg0) {
                    // IMPORTANT This is the Problem
                    GUI_1T1P.this.oSys1T1P.switchOn(); // returns "old" instead of "mimi"
                    // seems to be a completely diffrent instance of oSys1T1P
                    // oSys1T1P.switchOn(); // returns also "old"
          oJButton_running = new JButton("Run");
          oJButton_running.addActionListener( new ActionListener() {
               public void actionPerformed(ActionEvent arg0) {
                    // IMPORTANT This is the Problem
                    GUI_1T1P.this.oSys1T1P.start(); // also uses the wrong instance
                    // oSys1T1P.start(); // also uses the wrong instance
          // set positions
          // add elements to window
          // finalize
          oJFrame.pack();
          // init window
     public void hide() {
          oJFrame.setVisible(false);
}maybe its easy to you but i'm researching for it about two days ...
thank you for reading and answering.

Answer 1

okay then i ask it in the short way
public class MyClass extends AbstractClass {
    // System
    private AnyClass objectOfAnyClass = new AnyClass() {       
        public void aFunction() { // this is a redefined function
             System.out.print("new output"); //This was System.out.print("old output"); before
void bFunc() {
   objectOfAnyClass.aFunction(); //By calling aFunction here it prints "new output"
        ActionListener al = new ActionListener() {
            public void actionPerformed(ActionEvent arg0) {
                 objectOfAnyClass.aFunction(); // if i call it from here it prints "old output"
// Part where al is used
}  My question is simply: why does it print "old output" inside of the actionlistener?
Thanks and sorry ;(
