Checking the parity of a byte

For a byte, probably the quickest way is to create an array of 256 boolean that indicate for a given byte value whether it is even or odd parity. You only have to initialize the array when the containing class is loaded. At this point speed does not matter.

To fill the array you can use

static int parity(byte value)

{

int v = (value >> 4) ^ value;

v = (v >> 2) ^ v;

v = (v >> 1) ^ v;

return v & 0x1;

}

Sorry Sir. I was in work tension that was the main reason, but the idea which you gave is very great. I was trying to use that in my program. In future I won't repeat.
