Array class -- like c++ vector? memory + pointers

[Halsafar]

Now I find myself writing programs in Java and finding I hate the language.... Mostly the lacks of memory allocation, pointers, bitwise operations, dereference operator... So maybe someone can help me out here.

I need a container class which can store the reference of many objects of one type. Example:
class Asteroids <-- Simply Asteroid
class AsteroidContanier <-- A class to manage all asteroids via 1 array

Now, I think I must be missing something in this language because I cannot devise a way in my head to write my own array class similar to that of std::vector. Although I want to avoid writing my own array class and hopefully be told there is one within the Java Libraries. However I would like to know how it works.

See I need to be able to push() and pop()... Is this possible...

So my question becomes?

- How can I dynamically resize an array at runtime?
- Any recommended readings on this topic for Java?
