Method Summary
booleanempty()Tests if this stack is empty.
peek()Looks at the object at the top of this stack without removing it from the stack.
pop()Removes the object at the top of this stack and returns that object as the value of this function.
Pushes an item onto the top of this stack.
intReturns the 1-based position where an object is on this stack.

index, or returns -1 if the element is not found.voidInserts the specified object as a component in this vector at the specified
index.booleanTests if this vector has no components.
Returns an iterator over the elements in this list in proper sequence.
Returns the last component of the vector.

index, or returns -1 if the element is not found.Returns a list iterator over the elements in this list (in proper sequence).
Returns a list iterator over the elements in this list (in proper sequence), starting at the specified position in the list.
Removes the element at the specified position in this Vector.

voidSets the component at the specified
indexof this vector to be the specified object.voidSets the size of this vector.
intReturns the number of components in this vector.
subList(int fromIndex, int toIndex) Returns a view of the portion of this List between fromIndex, inclusive, and toIndex, exclusive.
Returns an array containing all of the elements in this Vector in the correct order.
<T> T[]Returns an array containing all of the elements in this Vector in the correct order; the runtime type of the returned array is that of the specified array.
Returns a string representation of this Vector, containing the String representation of each element.
