growable array of primitive type

Dear all ranchers,
The Vector and ArrayList accept object only, and I found it not convenient to use. So I wonder is there any easy way to do this in Java:
GrowableArray ga = new GrowableArray();
int tmp = ga.popBack();

Never do things the hard way if you don't have a good reason.

The J2SE Collections accept only Objects, as you've pointed out. I have noticed third party, open source, free Collections that work with primitives. You might want to try a quick search on Google. You could always write your own primitive Collection without too much work.
In the future, with Java 1.5, the compiler will autobox and unbox primitives as necessary. So, you'll be able to say myArrayList.add(13), and the compiler will step in and rewrite the code as myArrayList.add(new Integer(13)), saving us programmers some steps.

That's a good news. I'm looking forward to coding with JSDK 1.5!
I agree. Here's the link:
