Fastest way to check if a byte array is all zeros

Question

I have a byte[4096] and was wondering what the fastest way is to check if all values are zero?

Is there any way faster than doing:

byte[] b          


        

Answer 1

For Java 8, you can simply use this:

public static boolean isEmpty(final byte[] data){
    return IntStream.range(0, data.length).parallel().allMatch(i -> data[i] == 0);
}
