- true if the stack contains no items, false otherwise
peek
public T peek()
Returns the top Object on the stack without removing it.
- the top Object on the stack
pop
public T pop()
Pops an item from the stack and returns it. The item popped is
removed from the Stack.
- the Object popped from the stack
push
public T push(T item)
Pushes an Object onto the top of the stack. This method is effectively

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
