Method Detail

getStartTimeMillis

public static long getStartTimeMillis()

Returns the current system time so that we can determine the elapsed time later. The system time is returned after performing a garbage collection to make multiple timings more consistent.

getElapsedMillis

public static long getElapsedMillis(long lastTime)

Returns the number of milliseconds that have elapsed since lastTime.

Parameters:

lastTime - The time in milliseconds to compute the elapsed time from

See Also:

getElapsedSeconds(long), getElapsedString(long), displayElapsedString(java.applet.Applet, long)

getElapsedSeconds

public static double getElapsedSeconds(long lastTime)

Returns the number of seconds that have elapsed since lastTime.

Parameters:

lastTime - The time in milliseconds to compute the elapsed time from

getElapsedMillis(long), getElapsedString(long), displayElapsedString(java.applet.Applet, long)

getElapsedString

public static java.lang.String getElapsedString(long lastTime)

Returns a string containing the number of seconds that have elapsed since lastTime.

Parameters:

lastTime - The time in milliseconds to compute the elapsed time from

See Also:

getElapsedMillis(long), getElapsedSeconds(long), displayElapsedString(java.applet.Applet, long)

displayElapsedString

public static void displayElapsedString(java.applet.Applet applet,
                                        long lastTime)

Displays a string containing the number of seconds that have elapsed since lastTime.

Parameters:

applet - The applet to display the string in. If an applet is passed in, the string will be displayed in the Applet's status line, otherwise, the string will be written to System.out.

lastTime - The time in milliseconds to compute the elapsed time from
