Frame resets when label or text change

I am currently having some problem in some javaFrame application. It is a simple game where the ball is running around and there is one button which starts and stops the ball. The problem is whenever i change the text of a label or a button while the ball is running the frame resets(the ball is resetting where it was in the first place) and i don't want that to happen. I created the frame and the panel by dragging from the side(i did not write code to create frame and panels). I don't know all the rules in this site and i don't know if it is permissible but i could not find any ways to show this to you so i linked 2 short youtube videos at the end so you can see what it is(i apologize for that).
What i did in frame:
Created 2 panels.
Added a button to panel1(upper one) and added ball image on top of it.
Added 2 buttons on panel2(lower one) which are Start/Stop and changeLabel.

Frame without changing anything : https://www.youtube.com/watch?v=yC_8tyUmal0
Frame with changing the text : https://www.youtube.com/watch?v=zGvhCnRRTtw
EDIT:
If i create the frame on my own it works fine.
Why is that please help me thank you.

add KeyListener to JInternalFrame

Actually my registerKeyBoardAction with following code not working after I pressed Alt key for first time and again if I press Alt key it works means that Alt key is acting as a lock and unlock states i.e while in lock state keyBoard action doesnot work and in unlock state it works:

I have searched and found that if I consume the event on Alt key pressed then I will have problem fixed but I am unable to addKeyListener to JInternalFrame. Please! Help me and thanks in advance.

vlcj application optimization

Hi friends I'm actually developing my own video player, using VLCJ libraries , I use a canvas over a JFrame and a options bar with buttons to play,stop etc..
in this moment the video player and all the buttons works, but
it is so slow and the fps are so low too, I think that using a canvas is not the best method to play videos , or maybe my code is not optimized .
Main class:
package vlcvideo;
import java.io.File;
import javax.swing.JFileChooser;
public class VlcVideo {
static JFileChooser filex = new JFileChooser();
public static void main(String[] args)
{
String rutaVlc = "C:/vlc64/vlc";
String rutaVideo="/src/vlcVideo/c.mp4";
File ourFile;
//seleccionar la ruta de instalacion del vlc
/*filex.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);//selecciona solo directorios
filex.showSaveDialog(null);
ourFile=filex.getSelectedFile();
rutaVlc=ourFile.getAbsolutePath();*/
/*
filex.setFileSelectionMode(JFileChooser.FILES_ONLY);
filex.showSaveDialog(null);
ourFile=filex.getSelectedFile();
rutaVideo=ourFile.getAbsolutePath();*/
System.out.println(rutaVlc + "ruta DLL");
System.out.println(rutaVideo + " ruta video");
//new MediaPlayer(rutaVlc,rutaVideo).run();

You have a tight loop in your thread that will consume just about all of your CPU.
Rather than polling inside a tight loop you should use media player events to get the information you want.
Or at worst you should sleep in that loop.

Accessing elements from a jFrame that is within a running instance of a thread

I am trying to make an app for communicating between different running instances of a thread. I have a jFrame that has a jTextField and a jButton. In the jTextField I type the number of threads that I want to run and after I press the jButton the threads run. Each thread contains a jFrame with a jButton. So if I type 3 in the jTextField and then press OK, three different jFrames pop out that have an own jButton. If I press the jButton in one of the jFrames of the threads, the jButton is set to disabled (setEnabled(false)). This should happen to each jButton of the jFrames from within the threads when pressed but the one from the last jFrame that is still not pressed.
This is the window class for the thread:
public class Window extends JFrame implements Runnable {
JFrame jr;
JButton bt;
public void run() {
jr=new JFrame();
bt=new jButton();
bt.setTitle("Press Me");
jr.setLayout(new FlowLayout());
jr.add(bt);
bt.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e){
bt.setEnabled(false);
}
});
jr.setVisible(true);
}
}
Now this is how I run multiple instances of this thread. i is the number of the thread instances that is taken from the jTextField:
( int i=Integer.parseInt(jTextField1.gettext()) )
for (int a=0;a<i;a++) {
Runnable thr=new Window(a);
executor.execute(thr);
}
This is what I want to do: After I press the jButton on every jFrame that is within the thread instances and it is set to setEnabled(false) I get to the last jFrame that is popped up whose jButton is still unpressed. When I press this last JButton I want that all the JButtons on every jFrame to be set back to setEnabled(true). How can I do that?

This is the main class it works 100 % now!

I would seriously advise you to take a time out, and refactor all of your code. Igonoring that in the class new8, in method decode replace this code:
new vpsfame().ac.setText(t[1].substring(1,2));
System.out.println("Lattitude: "+t[3]);
System.out.println("Direction of Lattitude: "+t[4]);
new vpsfame().ab.setText(t[3].concat(t[4]));
System.out.println("Longitude: "+t[5]);
System.out.println("Direction of Longitude: "+t[6]);
new vpsfame().bc.setText(t[5].concat(t[6]));
System.out.println("Speed over Ground: "+t[7]);
new vpsfame().cd.setText(t[7]);
With this:
//use one object, dont just create new frames
vpsfame myFrame = new vpsfame();
myFrame.ac.setText(t[1].substring(1,2));
System.out.println("Lattitude: "+t[3]);
System.out.println("Direction of Lattitude: "+t[4]);
myFrame.ab.setText(t[3].concat(t[4]));
System.out.println("Longitude: "+t[5]);
System.out.println("Direction of Longitude: "+t[6]);
myFrame.bc.setText(t[5].concat(t[6]));
System.out.println("Speed over Ground: "+t[7]);
myFrame.cd.setText(t[7]);
//Also set the frame to visible, so it can be displayed once you've done all this work.
myFrame.setVisible(true);
The problem is that:
Firstly, you are creating multiple vpsframe objects where you should only have one. It makes no sense to create 5 frames where each will have 4 empty fields. Create one object and initialise all it's fields rather than using 5 diffrent objects.
You are not tracking the objects you are creating, the garbage collector will just get rid of the, so create one object, assign it to a variable and use that.
Set the vpsfame object to visible, otherwise you will never see it.
Your code also needs refactoring, you should be using the camelCase naming convention, and classes should always begin with Capital letters.
