Java BigInteger not() Method

The not() method of Java BigInteger class is used to find the Bitwise NOT of a BigInteger. This method returns a BigInteger whose value is ( ~this).

Syntax:

Parameter:

Returns:

This method returns ( ~this).

Exception:

Note: This method returns a negative value if and only if this BigInteger is positive.

Example 1

import java.math.BigInteger;
public class BigIntegerNotExample1{
public static void main (String[] args)
{
// create 2 BigInteger object
BigInteger big1,big2;
// assign value to big1
big1 = new BigInteger( "5" );  
// perform not operation on big1 
big2= big1.not();   
String str = "NOT operation on " + big1+ " gives " + big2;
System.out.println(str);   
}
}

Test it Now

Output:

NOT operation on 5 gives -6

Example 2

import java.math.BigInteger;
public class BigIntegerNotExample2{
public static void main (String[] args)
{
// create 2 BigInteger object
BigInteger big1,big2;
// assign value to big1
big1= new BigInteger("-5");  
// perform not operation on big1 
big2= big1.not();   
String str = "NOT operation on " + big1+ " gives " + big2;
System.out.println(str);   

}
}

Test it Now

Output:

NOT operation on -5 gives 4

Example 3

import java.math.BigInteger;
public class BigIntegerNotExample3{
public static void main (String[] args)
{
// create 2 BigInteger object
BigInteger big1,big2;
// assign value to big1
big1= new BigInteger("15");  
// perform not operation on big1 
big2= big1.not();   

String str = "NOT operation on " + big1+ " gives " + big2;
System.out.println(str);   

}
}

Test it Now

Output:
