public byte getBit(int position)
{
return (ID >> position) & 1;
}
Right shifting ID by position will make bit #position be in the furthest spot to the right in the number. Combining that with the bitwise AND &
with 1 will tell you if the bit is set.
position = 2
ID = 5 = 0000 0101 (in binary)
ID >> position = 0000 0001
0000 0001 & 0000 0001( 1 in binary ) = 1, because the furthest right bit is set.
