Usage:
				
		long one = 1l;
		int bitCountOne = Long.bitCount(one);
		System.out.println(bitCountOne);

		long zero = 0l;
		int bitCountZero = Long.bitCount(zero);
		System.out.println(bitCountZero);

		long minusone = -1l;
		int bitCountMinusOne = Long.bitCount(minusone);
		System.out.println(bitCountMinusOne);

		long max = Long.MAX_VALUE;
		int bitCountMax = Long.bitCount(max);
		System.out.println(bitCountMax);

		long min = Long.MIN_VALUE;

Loading...
Usage:
				
		Long one = 1l;
		byte oneByte = one.byteValue();
		System.out.printf("Byte value of 1 = 0x%02X \n", oneByte);

		Long zero = 0l;
		byte zeroByte = zero.byteValue();
		System.out.printf("Byte value of 0 = 0x%02X \n", zeroByte);

		Long minuesone = -1l;

		Long max = Long.MAX_VALUE;
		byte maxByte = max.byteValue();
		System.out.printf("Byte value of MAX = 0x%02X \n", maxByte);

		Long min = Long.MIN_VALUE;
