package com.tutorialspoint;

import java.math.*;

public class BigIntegerDemo {

   public static void main(String[] args) {

      // create 3 BigInteger objects
      BigInteger bi1, bi2, bi3;

      bi1 = new BigInteger("7");
      bi2 = new BigInteger("20");

      // multiply bi1 with bi2 and assign result to bi3
      bi3 = bi1.multiply(bi2);

      String str = bi1 + " * " + bi2 + " = " +bi3;

      // print bi3 value
      System.out.println("Multiplication result is " +str);
   }
}

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

Multiplication result is 7 * 20 = 140
