Algorithm Animation

• Use thread to make progress in algorithm
• Display algorithm state
• Example: Animate Ch9/animation/Sorter.java
  
• Sleeps inside compare method
• Pass custom comparator
  Comparator<Double> comp = new
     Comparator<Double>()
     {
        public void compare(Double d1, Double d2)
        {
           sleep
           return comparison result
        }
     };
