Method Detail
-
push
public E push(E item)
Pushes an item onto the top of this stack. This has exactly the same effect as:add(item)
- Parameters:
item
- the item to be pushed onto this stack.- Returns:
- the
item
argument. - See Also:
ArrayList.add(E, java.lang.Object[], int)
-
pop
public E pop()
Removes the object at the top of this stack and returns that object as the value of this function.- Returns:
- The object at the top of this stack (the last item of the ArrayList object).
- Throws:
EmptyStackException
- if this stack is empty.
-
peek
public E peek()
Looks at the object at the top of this stack without removing it from the stack.- Returns:
- the object at the top of this stack (the last item of the ArrayList object).
- Throws:
EmptyStackException
- if this stack is empty.
-
empty
public boolean empty()
Tests if this stack is empty.- Returns:
true
if and only if this stack contains no items;false
otherwise.
-
search
public int search(Object o)
Returns the 1-based position where an object is on this stack. If the object o occurs as an item in this stack, this method returns the distance from the top of the stack of the occurrence nearest the top of the stack; the topmost item on the stack is considered to be at distance 1. The equals method is used to compare o to the items in this stack.- Parameters:
o
- the desired object.- Returns:
- the 1-based position from the top of the stack where the object is
located; the return value
-1
indicates that the object is not on the stack.
