my own guess (and that's what it truly is), is that an ArrayList would be better unless you are worried about thready type things such as concurrency and synchronization, then go with vector. Anyone -- please correct if any errors.

thnx

I ran into this problem:

MyObject[] MyObjects = new MyObject[text.getItemCount()];

for (int i = 0; i < MyObjects.length; i++)

{

MyObjects[i] = new MyObject();

MyObjects[i].Load(Name, text.getItem(i)); // performs a procedure on my object, i get error here.

}

Nullpointerexception... What did i forget?

btw

- text (a list-textfile) was successfully loaded.

- when MyObject is created with hand the procedure Load works.

Looks like time to put a bunch of System.out.println() statements in. I'd pay particular attention to what text and what text.getItem(i) are at the time of the loop.
