What is Hash Table vs ArrayList: Key Differences about?

There are three main differences between arrays and stacks: 1. Arrays can be multi-dimensional while stacks are strictly one-dimensional. 2. With an array, any element can be directly accessed using its index. With a stack, only the top element is directly accessible - other elements must be accessed by popping elements off the stack. 3. Memory allocation for arrays is done at compile-time while stacks allocate memory at run-time. Arrays can result in wasted memory while stacks do not.
