copyOfRange
public static byte[] copyOfRange(byte[] original,

- Make a copy of a range of bytes from the passed in array. The range can extend beyond the end
of the input array, in which case the returned array will be padded with zeroes.
- Parameters:
original - the array from which the data is to be copied.from - the start index at which the copying should take place.to - the final index of the range (exclusive).- Returns:
- a new byte array containing the range given.
