Bit oriented operation

static int bitCount(int i)

Count the bits

static int highestOneBit(int i)

Returns an int value with at most a single one-bit, in the position of the highest-order ("leftmost") one-bit.

static int lowestOneBit(int i)

Returns an int value with at most a single one-bit, in the position of the lowest-order ("rightmost") one-bit.

public class Main {
  public static void main(String[] args) {

    System.out.println(Integer.bitCount(10));
    System.out.println(Integer.highestOneBit(10));
    System.out.println(Integer.lowestOneBit(10));
  }
}

The output:

2
