Example

The following example shows the usage of math.BigInteger.abs() method.

package com.tutorialspoint;

import java.math.*;

public class BigIntegerDemo {

   public static void main(String[] args) {

      // create 4 BigInteger objects
      BigInteger bi1, bi2, bi3, bi4;  

      // assign values to bi1, bi2
      bi1 = new BigInteger("123");
      bi2 = new BigInteger("-123");

      // assign absolute values of bi1, bi2 to bi3, bi4
      bi3 = bi1.abs();
      bi4 = bi2.abs();
	  
      String str1 = "Absolute value of " + bi1 + " is " + bi3;
      String str2 = "Absolute value of " + bi2 + " is " + bi4;

      // print bi3, bi4 values
      System.out.println( str1 );
      System.out.println( str2 );
   }
}

Let us compile and run the above program, this will produce the following result −

Absolute value of 123 is 123
Absolute value of -123 is 123
