      public int start()
      starts the stopwatch
      Returns:
      the time it took to start the stopwatch, typically very small

      public int stop()
      stops the stopwatch
      can be restarted with "start()"
      if stopwatch is not running, this is equivalent to reset()
      Returns:
      equivalent to read()

    • lap

      public int lap()
      laps the stopwatch
      if the stopwatch is not running, this is equivalent to start()
      Returns:
      equivalent to read()

    • read

      public int read()
      reads the value of this stopwatch
      Returns:
      value of this stopwatch

    • read

      public int read(int lap)
      reads the specific value of a lap on this stopwatch
      lap numbers start from 0
      Parameters:
      lap - the lap number
      Returns:
      the length of this lap
      equivalent to read(lap, false)

    • read

      public int read(int lap, boolean totalTime)
      reads the specific value of a lap on this stopwatch
      lap numbers start from 0
      Parameters:
      lap - the lap number
      totalTime - whether or not to count the total time since start()(true) or to count lap-to-lap(false)
      Returns:
      the length of this lap

    • reset

      public void reset()
      resets the stopwatch
      equivalent to writing (variable) = new Stopwatch();
