BigInteger clearBit() Method in Java

Prerequisite: BigInteger Basics
The clearBit() method returns a BigInteger which is used to clear a particular bit position in a BigInteger. The bit at index n of binary representation of BigInteger will be cleared means converted to zero. Mathematically we can say that it is used to calculate this & ~(1<<n).
Syntax: 
 

public BigInteger clearBit(int n)

Parameter: The method takes one parameter n which refers to the index of the bit needed to be cleared.
Return Value: The method returns the BigInteger after clearing the bit position n.
Throws: The method might throw an ArithmeticException when n is negative.
Examples: 
 

Input: value = 2300, index = 3
Output: 2292
Explanation:
Binary Representation of 2300 = 100011111100
bit at index 3 is 1 so clear the bit at index 3 
Now Binary Representation becomes 100011110100
and Decimal equivalent of 100011110100 is 2292

Input: value = 5482549, index = 0
Output: 5482548

Below program illustrate the clearBit(index) method of BigInteger(). 
 

/*
*Program Demonstrate clearBit() method of BigInteger 
*/
import java.math.*;

public class GFG {

    public static void main(String[] args)
    {

        // Creating  BigInteger object
        BigInteger biginteger = new BigInteger("5482549");

        // Creating an int i for index
        int i = 0;

        // Call clearBit() method on bigInteger at index i
        // store the return BigInteger
        BigInteger changedvalue = biginteger.clearBit(i);

        String result = "After applying clearbit at index " + 
        i + " of " + biginteger+" New Value is " + changedvalue;

        // Print result
        System.out.println(result);
    }
}

After applying clearbit at index 0 of 5482549 New Value is 5482548
