Stack
public Stack()
This constructor creates a new Stack, initially empty
empty
public boolean empty()
Tests if the stack is empty.
- true if the stack contains no items, false otherwise
push
public T push(T item)
Pushes an Object onto the top of the stack. This method is effectively
the same as addElement(item).
item - the Object to push onto the stack
- the Object pushed onto the stack
Vector.addElement(Object)
search
public int search(Object o)
Returns the position of an Object on the stack, with the top
most Object being at position 1, and each Object deeper in the
stack at depth + 1.
o - The object to search for
- The 1 based depth of the Object, or -1 if the Object
is not on the stack
Stack.java - Class that provides a Last In First Out (LIFO)
datatype, known more commonly as a Stack
