Equivalent of std::vector in Java?

Question

What would be the closest thing to a std::vector in Java? By this I mean, a class which can take in T into its constructor and then pushBack, popBack() and that is stored in

Answer 1

You're probably looking for the ArrayDeque which supports push/pop style access from both ends of the list efficiently.

Avoid Stack and Vector - these are synchronized, which implies generally pointless overhead.

ArrayList is also fine; however, you'd need to implement your own (trivial) pop method since it is not provided by the class itself. ArrayList does permit indexed access, which ArrayDeque lacks.
