# BigInteger xor() Method in Java

Prerequisite: BigInteger Basics The xor(BigInteger val) method returns bitwise-XOR of two bigIntegers. This method returns a negative BigInteger if and only if exactly one of the current bigInteger and the bigInteger passed in parameter id negative. The xor() method of BigInteger class apply bitwise-XOR operation upon the current BigInteger and BigInteger passed as parameter.

Syntax:

`public BigInteger xor(BigInteger val)`

Parameters: The method accepts one parameter val of BigInteger type and refers to the value to be XOR’ed with this BigInteger.

Return Value: The method returns bitwise-XOR of the current BigInteger with the BigInteger val

Examples:

```Input: value1 = 2300 , value2 = 3400
Output: 1460
Explanation:
Binary of 2300 = 100011111100
Binary of 3400 = 110101001000
XOR of 100011111100 and 110101001000 = 10110110100
Decimal of 10110110100 = 1460.

Input: value1 = 54298 , value2 = 64257
Output: 12059```

Below program illustrate the xor() method of BigInteger Class:

## Java

 `/*``*Program Demonstrate xor() method of BigInteger``*/``import` `java.math.*;` `public` `class` `GFG {` `    ``public` `static` `void` `main(String[] args)``    ``{` `        ``// Create 2 BigInteger objects``        ``BigInteger biginteger = ``new` `BigInteger("``2300``");``        ``BigInteger val = ``new` `BigInteger("``3400``");` `        ``// Call xor() method to find this ^ val``        ``BigInteger biggerInteger = biginteger.xor(val);` `        ``String result = "Result of XOR operation between " + biginteger + " and "``                        ``+ val + " is " + biggerInteger;` `        ``// Print result``        ``System.out.println(result);``    ``}``}`
