Tring to write a Multiplication method without using Biginteger.

I am trying to write a code that has multiplication method(n.multiply(n1) by using the linked array , stack or any other ways except using Biginteger. I don't know what to do.

ex)
   private static void test1 ( String s, String s2 )
   {
      ip n = new ip(s);
      ip n2 = n.multiply(n);
      System.out.println("\nTesting " + s + "\n" + ( n2.toString().equals(s2) ? "pass"  : "FAIL " ));
   }

To achieve something like in your example, all that's required is a type 'ip' with a multiply(ip) method

I wanrt to know the concept by using the linked list or any other various ways to write the code.

Not quite sure how a linked list would help you multiply. What is your assignment spec?

I can choose different ways to do it other than linked list.
I am trying to write a code for a class IPint(Infinite Precision Integer) which will represent integers with any number of digits.
I will be testing it with the test that was posted on my thread.

Oh OK. Yes - a linked list would help then. You can use LinkedList or ArrayList

I wanna know the concept of it. Also, where can I find the code for Biginteger in java compiler folder? I would like to study with it.

If you have the jdk installed, look for src.zip in the root installation folder. This contains most of the public api classes (including java.math.BigInteger)
