2.1: ArrayStack
2.1: ArrayStack - Fast Stack Operations Using an Array. An ArrayStack implements the list interface using an array a, called the backing array. The list element with index i is stored in a[i]. At most times, a is larger than strictly necessary, so an integer n is used to keep track of the number of elements actually stored in a. In this way ...

Aprende másArray or List in Java. Which is faster?
So what happens internally is new Array is created with the capacity. Till Java 6. int newCapacity = (oldCapacity * 3)/2 + 1; (Update) From Java 7. int newCapacity = oldCapacity + (oldCapacity >> 1); also, data from the old array is copied into the new array. Having overhead methods in ArrayList that''s why Array is faster than ArrayList.

Value types are either allocated on the stack, or part of an object on the heap. An array is an object. An array can only contain value types. An object reference is a value type. So, if you have an array of integers, the array is allocated on the heap and the integers that it contains is part of the array object on the heap.
Aprende másWhen to use static arrays vs dynamic arrays C
In this case, a general rule is to use a static size when you can: when the exact size is known at compile time, or. when an upper bound is known and using the upper bound will not waste too much space. In general, using a static size is more efficient because the compiler has more information and therefore has more opportunity for …
Aprende másDoes std::array<> guarantee allocation on the stack only?
Some may be more satisfied by what we can get on cppreference: std::array is a container that encapsulates fixed size arrays. This container is an aggregate type with the same semantics as a struct holding a C-style array T[N] as its only non-static data member. Thirdly, std::array was introduced in C++11.

Aprende másUsing Dynamically Allocated Arrays in a Class Storage structure
In general, calling something a list doesn''t make it a list. A datatype is effectively defined by its behavior, the semantics of its methods. A container where you can add and remove elements only at one point is usually called a stack. In your example, only the commented-out DeleteItem method differs from the methods of a stack container. –
