Java XOR over two arrays [closed]

Question

I have to apply an xor over two arrays like let's say I have :

array_1: 1 0 1 0 1 1
array_2: 1 0 0 1 0 1

I would like to have a function that accepts two arrays and returns an array applying the XOR, so in this case I would like this function to return:

returned_array: 0 0 1 1 1 0

Please help me with an algorithm .. Thanks !

If you are storing these numbers in byte arrays, use this straightforward solution:

byte[] array_1 = new byte[] { 1, 0, 1, 0, 1, 1 };
byte[] array_2 = new byte[] { 1, 0, 0, 1, 0, 1 };

byte[] array_3 = new byte[6];

int i = 0;
for (byte b : array_1)
    array_3[i] = b ^ array_2[i++];

Output array:

0 0 1 1 1 0
