Java BigInteger example

BigInteger class provides us operations for modular arithmetic (such as add, subtract) , prime generation , bit manipulation and many other useful operations.

Here in this example of BigInteger we have created two big integer variables and we are going to multiply them and will store that result in another BigInteger variable. Here is the full example code of BigIntegerExample.java as follows:

BigIntegerExample.java


import java.math.BigInteger;

public class BigIntegerExample 

{

  public static void main(String[] args) 

  {

  BigInteger bigInteger1 = new BigInteger ("123456789");

  BigInteger bigInteger2 = new BigInteger ("112334");

  BigInteger bigIntResult =

    bigInteger1.multiply(bigInteger2); 

  System.out.println("Result is  ==> " + bigIntResult);

  }

}

Output of the above program is as follows:

C:\biginteger>javac BigIntegerExample.java

C:\biginteger>java BigIntegerExample
Result is ==> 13868394935526
