public class RelativeTime

extends java.lang.Object

This util class contains several methods and constants to manipulate relative time values. The relative time value has to be provided as either one integer value (representing the time in milliseconds), or as a set of time attribute integers (hours,minutes,seconds and milliseconds).

RelativeTime

public RelativeTime()

Method Detail

getHours

public static int getHours(int timeValue)

Retrieves the amount of hours that are left in the timeValue variable (representing the time in milliseconds).

Parameters:

timeValue - An integer which holds the relative time value.

Returns:

The amount of hours left.

getMinutes

public static int getMinutes(int timeValue)

Retrieves the amount of minutes that are left in the timeValue variable (representing the time in milliseconds).

Parameters:

timeValue - An integer which holds the relative time value.

Returns:

The amount of minutes left.

getSeconds

public static int getSeconds(int timeValue)

Retrieves the amount of seconds that are left in the timeValue variable (representing the time in milliseconds).

Parameters:

timeValue - An integer which holds the relative time value.

Returns:

The amount of seconds left.

getMillis

public static int getMillis(int timeValue)

Retrieves the amount of milliseconds that are left in the timeValue variable (representing the time in milliseconds).

Parameters:

timeValue - An integer which holds the relative time value.

Returns:

The amount of milliseconds left.

convertIntToTime

public static java.lang.String convertIntToTime(int timeValue)

Converts an integer (representing the time in milliseconds) to a string (like "12:42:15.020")

Parameters:

time - The amount of time in milliseconds.

Returns:

String containing the amount of time in the "h:m:s.ms" format.

convertTimeToInt

public static int convertTimeToInt(int h,
                                   int m,
                                   int s,
                                   int ms)

Converts the time attribute values to one integer representing the time in milliseconds.

Parameters:

h - The amount of hours

m - The amount of minutes

s - The amount of seconds

ms - The amount of millis

Returns:

The amount of time in milliseconds OR -1 if the timeValue contains negative values.

convertTimeToInt

public static int convertTimeToInt(java.lang.String time)

Converts a string (like "12:42:15.020") to milliseconds

Parameters:

time - A string which contains the relative time in the format "hours:minutes:seconds.millis"

Returns:

The amount of time in milliseconds OR -1 if one of the time attributes provided is invalid.

main

public static void main(java.lang.String[] args)
