Class Timer

java.lang.Object
  harpoon.Util.Timer

public class Timer
extends Object

Timer keeps track of how much time accumulates between successive calls to start and stop. This is useful when profiling the compiler. Timer t = new Timer(); for (int i=0; i<10; i++) { bar(); t.start(); foo(); t.stop(); } System.out.println(t.timeElapsed()); This prints the total time spent in foo in milliseconds.
