Usage

From source file:Main.java

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);/*from w w  w  .  j a  va 2s.  com*/
    System.out.println(i2);
}

From source file:Main.java

public static void main(String[] args) {

    BigInteger bi1 = new BigInteger("7");
    BigInteger bi2 = new BigInteger("-7");

    // perform bitlength operation on bi1, bi2
    int i1 = bi1.bitLength();
    int i2 = bi2.bitLength();

    System.out.println(i1);//w  w  w .  j  a  v  a  2s.c  o m

}

From source file:Main.java

    // perform bitcount operation on bi1, bi2
    int i1 = bi1.bitCount();
    int i2 = bi2.bitCount();

    System.out.println(i1);// www  .j a va2 s. co  m
    System.out.println(i2);
}

From source file:Main.java
