Java BigInteger setBit() Method

The setBit() method of Java BigInteger class is used to set the bit position. This method returns a BigInteger whose value is equivalent to this BigInteger with the designated bit set.

Syntax:

Parameter:

n- Index of the bit to set entered by the user.

Returns:

This method returns ( this | (1<<n)).

Exception:

ArithmeticException - n is negative.

Example 1

import  java.math.BigInteger;
public class BigIntegerSetBitExample1{
public static void main(String[] args){
// create 2 BigInteger object
BigInteger big1,big2;
// assign value to big1
big1= new BigInteger("5");  // 0101
// perform setbit operation on big1 
// assume index n is 1
big2= big1.setBit(1);   // 0111

String str = " SetBit operation on " + big1+ " at index 1 gives " + big2;
System.out.println(str);   
}
}

Test it Now

Output:

SetBit operation on 5 at index 1 gives 7

Example 2

import  java.math.BigInteger;
public class BigIntegerSetBitExample2{
public static void main(String[] args){
// create 2 BigInteger object
BigInteger big1,big2;
// assign value to big1
big1= new BigInteger("5");  // 0101
// perform setbit operation on big1 
// assume index n is  -1
big2= big1.setBit(-1);   

String str = " SetBit operation on " + big1+ " at index  -1 gives " + big2;
System.out.println(str);   
}
}

Test it Now

Output:

java.lang.ArithmeticException: Negative bit address

Example 3

import java.math.BigInteger;
public class BigIntegerSetBitExample3{
public static void main(String[] args){
// create 2 BigInteger object
BigInteger big1,big2;
// assign value to big1
big1= new BigInteger("5");  // 0101
// perform setbit operation on big1 
// assume index n is  2
big2= big1.setBit(2);   // 0101

String str = " SetBit operation on " + big1+ " at index  2 gives " + big2;
System.out.println(str);   

}
}

Test it Now

Output:

SetBit operation on 5 at index 2 gives 5
