getMilliseconds

public long getMilliseconds()

Returns the duration of the stopwatch as a long, in milliseconds. The duration starts when the stopwatch is first started using start() and is finished when the stopwatch is lastly stopped using stop(), or when this method is called if the stopwatch was not stopped since most recently started.

Returns:

the duration of the stopwatch, in milliseconds, since it was started until it was stopped (or until this method is called if it was not stopped)

getSeconds

public double getSeconds()

Returns the duration of the stopwatch as a double, in seconds. The duration starts when the stopwatch is first started using start() and is finished when the stopwatch is lastly stopped using stop(), or when this method is called if the stopwatch was not stopped since most recently started.

Returns:

the duration of the stopwatch, in seconds, since it was started until it was stopped (or until this method is called if it was not stopped)

getMinutes

public double getMinutes()

Returns the duration of the stopwatch as a double, in minutes. The duration starts when the stopwatch is first started using start() and is finished when the stopwatch is lastly stopped using stop(), or when this method is called if the stopwatch was not stopped since most recently started.

Returns:

the duration of the stopwatch, in minutes, since it was started until it was stopped (or until this method is called if it was not stopped)

isGoing

public boolean isGoing()

Returns whether or not the stopwatch is currently active (has been started but not stopped since the most recent start() call)

Returns:

true if stopwatch is currently active (has been started but not stopped since the most recent start() call), and false otherwise
