Actually, I also used BigInteger for that problem :

Scanner scan = new Scanner(System.in);
// storing the line as a String
String temp = scan.nextLine();
BigInteger bigInt= new BigInteger(temp);

// one thing that you have to be aware is when you add 2 BigInteger:

// suppose you have firstNumber and secondNumber, it will be

firstNumber.add(secondNumber);

BigInteger is capable of storing integer (i.e. non-fractional numbers) of any size.
