Question

I think I need a utility method like this:

public static short bitValue(int intNum, short pos)
{
    short bitValue = 0;

    //check pos bit (from right to left) in the intNum integer to see its value is 0 or 1
    //And then update the bitValue for return

    return bitValue;
}

I am doing research to learn how to do it now. If anyone of you guy have code in hand, please share with me. thanks

Answer 1

Just do a shift and mask:

return (short) ((intNum >> pos) & 1);

That’s assuming you want a return value of 1 or 0, of course. If you want bit itself, still with the same value, you’ll need to change your return type to int and use:

return intNum & (1 << intNum);
