public class Main {

  public static void main(String[] args) {

    BigInteger bi1 = new BigInteger("8");// 1000
    BigInteger bi2 = new BigInteger("7");// 0111

    // perform getLowestSetBit on bi1, bi2
    int i1 = bi1.getLowestSetBit();
    int i2 = bi2.getLowestSetBit();

    System.out.println(i1);
    System.out.println(i2);
  }
