- Method Detail
  - start
```
public void start()
```
    Start the stopwatch. Only a stopped stopwatch can be started.
  - stop
```
public void stop()
```
    Stop the stopwatch and store elapsed time. Only a running stopwatch can be stopped.
  - resume
```
public void resume()
```
    Start the stopwatch, but instead of starting from 0, it starts from the previous elapsed time. If the stopwatch has never been started, it is equivalent to start(). Only a stopped stopwatch can be resumed.
  - restart
```
public void restart()
```
    Stop and restart the stopwatch. Only a running stopwatch can be restarted.
  - isRunning
```
public boolean isRunning()
```
    Returns:
    
    Whether the stopwatch is running.
  - getElapsedNanoseconds
```
public long getElapsedNanoseconds()
```
    If the stopwatch is running: return elapsed time since the stopwatch has been started. If the stopwatch is stopped: return time for which the stopwatch has been running.
  - getElapsedMilliseconds
```
public long getElapsedMilliseconds()
```
    Returns:
    
    Same as getElapsedNanoseconds(), but the time is in milliseconds.
  - getElapsedSeconds
```
public long getElapsedSeconds()
```
    Returns:
    
    Same as getElapsedNanoseconds(), but the time is in seconds.
