intsetBit(int number, int count, boolean value)
set Bit 
if (value) {
    return setBit(number, count);
return clearBit(number, count);
booleanisBitSet(int b, int bit)
is Bit Set 
if (bit < 0 || bit >= 32)
    return false;
return (b & (1 << bit)) > 0;
booleanisBitSet(int number, int count)
is Bit Set 
return (number & (0x01 << count)) > 0;
booleanisPowerOfTwo(int v)
