    Hi Moni - an array is of fixed length determined when you create it. If you want to have a more flexible structure that will increase its size automatically as you add more inputs, you might want to consider ArrayList. They work just like arrays, except you cannot use them with the primitive types such as int. Hence, there are wrapper classes that can be used to store primitives in ArrayLists. The constructor is:
    Java Code:
    ArrayList<Integer> array = new ArrayList<Integer>();
    To access an element at index 2, for example, you will do:

    Java Code:
    array.get(2);
    For a complete method listing, please see the Java Api : ArrayList (Java Platform SE 6)

    BEst,
