java.util.EmptyStackException - if the stack is empty

empty

public boolean empty()

Tests if the stack is empty.

Returns:

true if the stack contains no items, false otherwise

search

public int search(java.lang.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.
