# BigInteger and() Method in Java

Last Updated : 12 Dec, 2021

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 ANDâ€™ed with the current BigInteger.
Return Value: The method returns the value of bitwise-AND of two BigIntegers.
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.

## Java

 `/*` `*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`
