It returns an int with the nth and mth bytes of x swapped x is just a normal integer, set to any value. n and m are integers between 0 and 3. For example, let the hex representation of x be 0x12345678, n is 0, and m is 2. The last and 3rd to last byte are supposed to be switched (n = 78, m = 34). Splet23. okt. 2024 · * first get the bytes needed to swap: n_byte and m_byte, which * seperately present nth byte of x and mth byte of y. * then set y = n_byte ^ m_byte. * because y ^ n_byte = n_byte ^ m_byte ^ n_byte = m_byte, * same as y ^ m_byte, so x ^= y << n will set nth byte to m_byte, * and x ^= y << m will set mth byte to n_byte. */ int y = 0; n = n << 3;

SpletAdd a comment. 1. If you are wanting a byte, wouldn't the better solution be: byte x = (byte) (number >> (8 * n)); This way, you are returning and dealing with a byte instead of an int, so we are using less memory, and we don't have to do the binary and operation & 0xff just to mask the result down to a byte.
