Creating a dynamic Integer Array

Question

Hi there.
This may seem trivial, but how do I create a dynamic array to store integers?
I tried Integer integerArray [] = new Integer (); but i get Cannot Resolve Symbol Error.
I am using Java 1.4.2 version.
Any suggestions would be helpful. Thanks

Doesnt an ArrayList store values as
String? Even if i did use Integer.parseInt to cast to
Integer from String doesnt it become tricky if i have
to do much calculations?Hi,
An ArrrayList can store any object you wish not just String. All you need to specify when retrieving an object is the type of object you want.
For example, if you have an ArrayList of integers an you want to retrieve an integer from the list you would use:-
int myInt = (int)myArrayList.get(myIndex);Therefore if you want to store an arbitrary object foo in an ArrayList the code is thus:-
//replace foo with the object you are storing.
foo foobar = (foo)myArrayList.get(myIndex);There is a slight change with ArrayLists in Java 5 where you should declare the objects that should be stored in the list but hopefully the above helps you to understand that an ArrayList or any other Collection as it happens can store objects of your choosing.
