Method Detail

valueAt

public static int valueAt(int[] array,
                          int key)

Searches the specified array of ints for the specified value using the sequential search algorithm. The array must be sorted prior to making this call.

Parameters:

array - the array to be searched.

key - the value to be searched for.

Returns:

index of the search key, if it is contained in the array; otherwise, array.length.

valueAt

public static int valueAt(java.lang.Object[] array,
                          java.lang.Object key)

referenceAt

public static int referenceAt(java.lang.Object[] array,
                              java.lang.Object key)

in

public static boolean in(java.lang.Object[] array,
                         java.lang.Object obj)

Return true if an object equal to obj is contained in array.

getDateString

public static java.lang.String getDateString()

Return a stringified date value. The format is as follows:

yyyymmdd

Returns:

A string representation of the current date.

getTimeString

public static java.lang.String getTimeString()

Return a stringified clock time value. The format is as follows:

hhmmss

Returns:

A string representation of the current time.

getDateTimeString

public static java.lang.String getDateTimeString()

Return a stringified date and clock time value. The format is as follows:

yyyymmdd-hhmm

Returns:

A string representation of the current date and time.

byte2str

public static java.lang.String byte2str(byte value)

Converts the given byte value to a string value aligned to three characters; it can be used to make message outputs print nicely.

sleep

public static void sleep(long time)

Wrapper for the Thread.sleep() method.

Parameters:

time - the time in milliseconds to sleep.
