How to convert a byte array to a hex string in Java?

Question

I have a byte array filled with hex numbers and printing it the easy way is pretty pointless because there are many unprintable elements. What I need is the exact hexcode in

If you're looking for a byte array exactly like this for python, I have converted this Java implementation into python.

class ByteArray:

@classmethod
def char(cls, args=[]):
    cls.hexArray = "0123456789ABCDEF".encode('utf-16')
    j = 0
    length = (cls.hexArray)

    if j < length:
        v = j & 0xFF
        hexChars = [None, None]
        hexChars[j * 2] = str( cls.hexArray) + str(v)
        hexChars[j * 2 + 1] = str(cls.hexArray) + str(v) + str(0x0F)
        # Use if you want...
        #hexChars.pop()

    return str(hexChars)

array = ByteArray()
print array.char(args=[])
