Ok, so my problem is this: I did a little java program to take the number of seconds from a text box and sleep a thread for that amount of seconds. Just to make it clear, here is the piece of code I used:
java Syntax (Toggle Plain Text) 
  1. jTestare.addActionListener(new ActionListener() {
  2. 					public void actionPerformed(ActionEvent evt) {
  3. 						try {
  4. 							Thread.sleep((Integer.parseInt(getStringInterval())));
  5. 						} catch (InterruptedException ex) {
  6. 							ex.printStackTrace();
  7. 						}
  8. 						getLblReprGrafica().setOpaque(true);
  9. 				                getLblReprGrafica().setBackground(Color.RED);
  10. 						getLblProcent().setText("100%");
  11. 					}
  12. 				});
Now my problem is how can I make this piece of code shared by a bunch of buttons (without them interfering with one another, like in starting one thread, moving two text boxes to the right, inputing a value then hitting Run on the respective button, and so on). I don't know if this can be done, but it was given to me as an assignment a couple of years ago and I only did it with one thread.

Im not sure I understand your question, but anyway...
First of all, it looks like you're sleeping the main thread, which will cause your application to freeze for a number of seconds.
I might be off here but do you want to fire a new thread for each button but avoid write reduntant code? If so, then create a class that extends Thread and fire it with method start()

java Syntax (Toggle Plain Text) 
  1. public class MyThread extends Thread {
  2.   public MyThread(/*argument here if needed*/) {
  3.   }
  4.  
  5.   public void run() {
  6.     try {
  7.      Thread.sleep(sleepTime);
  8.     }catch(InterruptedException ie) {
  9.     }
  10.     // Do something here
  11.   }
  12. }

fire the thread like:
java Syntax (Toggle Plain Text) 
  1. new MyThread().start();
---------------------------
