Syntax:

Parameter:

Returns:

This method returns the absolute value of the called value i.e. abs(this).

Example

import java.math.BigInteger;
public class BigIntegerAbsExample {
public static void main(String[] args){
BigInteger big1, big2, big3, big4;  // create 4 BigInteger objects
big1=new BigInteger("345");// assign value to big1 
big2=new BigInteger("-345");    // assign value to big2
big3=big1.abs ();        // assign absolute value of big1 to big 3
big4=big2.abs ();       // assign absolute value of big 2 to big 4.

String str1 = "Absolute value of" + big1 + "is" + big3;
String str2 = "Absolute value of" + big2 + "is" + big4;

// print big3, big4 values
System.out.println(str1);
System.out.println(str2 );
} 
}

Test it Now

Output:

Absolute value of  345 is 345
Absolute value of  -345 is 345
