public class Timer

extends java.lang.Object

This class implements a timer. The timer can be in one of two states: started or stopped. Method start() makes a transition from stopped to started, and method stop() does a transition from started to stopped. Method time() can be used to get the total time measured by the timer and it can be called when the timer is in either of the two states. Method reset() will reset the timer; if the timer was running then it will continue to run but it will measure time from the moment we called reset(), if the timer was stopped, the time measured will be reset to 0.

time

public long time()

This method should be called to find out the time measured so far. If the timer is started then the time measured up to this precise moment will be returned. If the timer was stopped then the time measured up to the time it was stopped will be returned. The time is measured in milliseconds.

Returns:

the measured time in milliseconds

isStarted

public boolean isStarted()

This method should be called to find out if the timer is started or not.

Returns:

true if timer is started, false otherwise
