bytesToHexString

public static String bytesToHexString(byte[] bytes)

This method builds a string by concatenating the 2 character hexadecimal representation of each byte from the input byte array.

For example: an input byte array containing: bytes[0] = 'a' bytes[1] = 'b' bytes[2] = 'c' bytes[3] = '-' bytes[4] = '1' bytes[5] = '2' bytes[6] = '3' returns the string "6162632d313233"

Parameters:

bytes - The byte array to convert to string

Returns:

The hexadecimal representation of the byte array. If bytes is null, the string "" is returned
