java thread: animate numerical model

[znaps]

You might want to look into the SwingUtilities.invokeLater() method. This lets you integrate some Runnable code into the Swing UI thread without messing up anything.

Something like

//....
// Your thread code here
//...
// Then when you're ready to update the UI:-
SwingUtilities.invokeLater(new Runnable(){
  public void run(){
     // Code to update UI
  }
});
