Java Stack push() vs add()

Question

I am trying to use Stack, but I am slightly confused by the terminology.

I find that Stack class has only push(E e) as per Java doc.

And has add(E e) and addAll(Collection<? extends E> c) as a inherited method from Vector class.

Do they have the same functionality or is it better to use push(...) to insert elements to the Stack object.

In other words, will I encounter any issues if I use add(...) instead of push(...)?

Definitly, you will not encounter any issues, because add is part of List interface as well as the Stack, but you should to notice the further readability of your code and your intentions in it by other programmers. push method will give them a clue that they're using the Stack object, they will know certantly what to expect from. Also notice that push has different return value than add (the former has "pushed object" type and the latter just a boolean response)

Answer 2

They are the same.

From the JavaDoc:

Pushes an item onto the top of this stack. This has exactly the same effect as:

addElement(item)
