Java.math.BigInteger.flipBit() Method
Description
The java.math.BigInteger.flipBit(int n) returns a BigInteger whose value is equivalent to this BigInteger with the designated bit flipped. It computes (this ^ (1<<n)).
Declaration
Following is the declaration for java.math.BigInteger.flipBit() method.
public BigInteger flipBit(int n)
Parameters
n − Index of bit to flip.
Return Value
This method returns a BigInteger object whose value is, this ^ (1<<n).
Exception
ArithmeticException − n is negative.
Example
The following example shows the usage of math.BigInteger.flipBit() 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("8");//1000 // perform flipbit operation on bi1 with index 1 bi2 = bi1.flipBit(1); String str = "Flipbit operation on " +bi1+ " at index 1 gives " +bi2; // print bi2 value System.out.println( str ); } }
Let us compile and run the above program, this will produce the following result −
Flipbit operation on 8 at index 1 gives 10
