Random in stack

Question

How can I pick random number in stack?

Answer 1

If you are talking about the “stack” data structure then you can’t. The whole point of a stack is to access the value of ONE element at a time from the ‘top’ of the stack a.k.a the last element that was appended to it. So in order to pick a random number from a list of values use an array or ArrayList and use the standard random package supplied with Java.
