Java

In Java, implement a Stack Interface to make a class that would be a standard Stack class; making sure that your implementation supports Generics . That is, one implementation which will support the storing of any kind of data. Your class will be implemented using Arrays. So as you know that arrays are immutable thus resizing is impossible; your implementation should support both Tight and Growth strategy. Your object should use either or depending on what the user asks for. You could also just use Growth as default unless the users requests for Tight strategy.
