# BigInteger and() Method in Java

• Last Updated : 04 Dec, 2018

The java.math.BigInteger.and(BigInteger val) method returns a BigInteger whose value is bitwise-AND of two BigIntegers. This method returns a negative number if both of the BigIntegers are negative. The and() method applies bitwise-AND operation upon the current bigInteger and bigInteger passed as parameter.

Syntax:

`public BigInteger and(BigInteger val)`

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

Return Value: The method returns the value of bitwise-AND of two BigIntegeres.

Examples:

```Input: value1 = 2300, value2 = 3400
Output: 2120
Explanation:
Binary of 2300 = 100011111100
Binary of 3400 = 110101001000
AND of 100011111100 and 110101001000 = 100001001000
Decimal of 100001001000 = 2120.

Input: value1 = 432045, value2 = 321076
Output: 296484
```

Below program is used to illustrate the and() method of BigInteger.

 `/*``*Program Demonstrate and() method of BigInteger ``*/``import` `java.math.*;`` ` `public` `class` `GFG {`` ` `    ``public` `static` `void` `main(String[] args)``    ``{`` ` `        ``// Creates 2 BigInteger objects``        ``BigInteger biginteger = ``new` `BigInteger(``"2300"``);``        ``BigInteger val = ``new` `BigInteger(``"3400"``);`` ` `        ``// Call and() method to find this & val``        ``BigInteger biggerInteger = biginteger.and(val);`` ` `        ``String result = ``"Result of AND operation between "` `+ biginteger + ``" and "``                        ``+ val + ``" is "` `+ biggerInteger;`` ` `        ``// Print the result``        ``System.out.println(result);``    ``}``}`
Output:
```Result of AND operation between 2300 and 3400 is 2120
```
