# BigInteger abs() Method in Java

prerequisite : BigInteger Basics The java.math.BigInteger.abs() method returns absolute value of a BigInteger. By using this method one can find absolute value of any large size of numerical data stored as BigInteger. Syntax:
`public BigInteger abs()`
Parameters: The method does not take any parameters. Return Value: The method returns the absolute value of a BigInteger. Examples:
```Input: -2300
Output: 2300
Explanation:
Applying mathematical abs() operation on
-2300, positive 2300 is obtained i.e |-2300| = 2300.

Input: -5482549
Output: 5482549
```
Below program illustrates abs() method of BigInteger:
 `// Below program illustrates the abs() method ``// of BigInteger  `` ` `import` `java.math.*; `` ` `public` `class` `GFG { `` ` `public` `static` `void` `main(String[] args) { `` ` `        ``// Create BigInteger object ``        ``BigInteger biginteger=``new` `BigInteger(``"-2300"``); ``         ` `        ``// abs() method on bigInteger to find the absolute value ``        ``// of a BigInteger ``        ``BigInteger absolutevalue= biginteger.abs(); ``             ` `        ``// Define result ``        ``String result =``"BigInteger "``+biginteger+ ``            ``" and Absolute value is "``+absolutevalue; ``        ``// Print result  ``        ``System.out.println(result); ``     ` `    ``} ``} `

Output:
```BigInteger -2300 and Absolute value is 2300
```
