the string

doesArrayBeginWith

public static boolean doesArrayBeginWith(byte[] array,
                         byte[] prefix)

Checks to see if a byte arry starts with another byte array.

Parameters:

array - the array

prefix - the prefix

Returns:

true, if successful

getIntFrom2ByteArray

public static int getIntFrom2ByteArray(byte[] input)

Converts a byte array with a length of 2 into an int

Parameters:

input - the input

Returns:

the int from the array

getIntFromByte

public static int getIntFromByte(byte bite)
