Java.math.BigInteger.clearBit() Method
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
