Advertisements


Description

The java.math.BigInteger.clearBit(int n) returns a BigInteger whose value is equivalent to this BigInteger with the designated bit cleared. It computes (this & ~(1<<n)).

Declaration

Following is the declaration for java.math.BigInteger.clearBit() method

public BigInteger clearBit(int n)

Parameters

  • n - index of bit to clear

Return Value

This method returns a BigInteger object of value, this & ~(1<<n)

Exception

  • ArithmeticException - n is negative

Example

The following example shows the usage of math.BigInteger.clearBit() method

package com.tutorialspoint;

import java.math.*;

public class BigIntegerDemo {

   public static void main(String[] args) {

	// create 2 BigInteger objects
	BigInteger bi1, bi2;  

	// assign value to bi1
	bi1 = new BigInteger("7"); 
	
	// perform clearbit operation on bi1 with index 2
	bi2 = bi1.clearBit(2);
		  
	String str = "Clearbit operation on " +bi1+ " at index 2 gives " +bi2;

	// print bi2 value
	System.out.println( str );
   }
}

Let us compile and run the above program, this will produce the following result:

Clearbit operation on 7 at index 2 gives 3
