BigInteger clearBit() in Java

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

Syntax:

BigInteger java.math.BigInteger.clearBit(int n)

This method takes one argument of type int as its parameter. It returns a BigInteger whose value is equivalent to this BigIntegerwith the designated bit cleared.(Computes (this & ~(1<<n)).)

Parameters: One parameter is required for this method.

n: index of the bit to clear.

Returns: this & ~(1<<n). 

Throws: ArithmeticException - n is negative.

For Example:

BigInteger bigInteger = new BigInteger("1234")

n = 4

bigInteger.clearBit(n) = > It returns 1218.

Approach

Java

import java.math.BigInteger;

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

        BigInteger bigInteger = new BigInteger("1234");
        int n = 4;
        System.out.println(bigInteger.clearBit(n));
    }
}

Output:

1218
