Selection Sort Algorithm Animation: Implementation

• Use a lock to synchronize access to the shared state
• Add a component instance field to the algorithm class and augment the constructor to set it
• That instance field is needed for
  • Repainting the component, and
  • Finding out the dimensions of the component when drawing the algorithm state

public class SelectionSorter
{
   public SelectionSorter(int[] anArray, JComponent aComponent)
   {
      a = anArray;
      sortStateLock = new ReentrantLock();
      component = aComponent;
   }
   . . .
   private JComponent component;
}
