BigInteger getLowestSetBit() in Java

getLowestSetBit(): This method is available in java.math.BigInteger class of Java.

Syntax:

int java.math.BigInteger.getLowestSetBit()

This method returns the index of the rightmost (lowest-order) one bit in this BigInteger (the number of zero bits to the right of the rightmost one bit). Returns -1 if this BigInteger contains no one bit.(Computes (this == 0? -1 : log2(this & -this)).)

Returns: index of the rightmost one bit in this BigInteger.

For Example:

BigInteger bigInteger = new BigInteger("1234")

bigInteger.getLowestSetBit() = > It returns 1.

Approach

Java

import java.math.BigInteger;

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

        BigInteger bigInteger = new BigInteger("1234");
        System.out.println(bigInteger.getLowestSetBit());

    }
}

Output:

1
