# BigInteger andNot() Method in Java

• Last Updated : 03 Jan, 2019

The java.math.BigInteger.andNot(BigInteger val) method returns a BigInteger whose value is (this & ~val) where this to the current BigInteger with which the function is being used and val is the bigInteger passed to the function as a parameter. This method, which is equivalent to and(val.not()), is provided as a convenience for masking operations. This method returns a negative BigInteger if and only if this is negative and val is positive. The andNOT() method apply bitwise AND operation upon the current bigInteger and NOT value of bigInteger passed as parameter.

Syntax:

`public BigInteger andNot(BigInteger val)`

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

Return Value: The method is used to return (this & ~val) where this to the current BigInteger with which the function is being used and val is the bigInteger passed to the function as a parameter.

Examples:

```Input: value1 = 2300, value2 = 3400
Output: 180
Explanation:
Binary of 2300 = 100011111100
Not of 3400 in binary signed 2's complement is 1111001010110111
AND of 100011111100 and 1111001010110111= 10110100
Decimal of 10110100 = 180.

Input: value1 = 432045, value2 = 321076
Output: 135561
```

Below program illustrate the andNot() method of BigInteger.

 `/* ` `*Program Demonstrate notNot() 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 andNot() method to find this & ~val ` `        ``BigInteger finalvalue = biginteger.andNot(val); ` `        ``String result = ``"Result of andNot operation between "` `+  ` `        ``biginteger + ``" and "``+ val + ``" is "` `+ finalvalue; ` ` `  `        ``// Print the result ` `        ``System.out.println(result); ` `    ``} ` `} `

Output:

```Result of andNot operation between 2300 and 3400 is 180
