Stack

stack继承Vetor

• add

  public boolean add(E e)

  Appends the specified element to the end of this Vector.

• push

  public E push(E item)

  Pushes an item onto the top of this stack. This has exactly the same effect as:

   addElement(item)

push和add都可以向stack中添加元素，不同的是push是stach本身方法，add是继承于vetor的

• pop

  public E pop()

  Removes the object at the top of this stack and returns that object as the value of this function.移除栈顶元素并返回

• peek

  public E peek()

  Looks at the object at the top of this stack without removing it from the stack.返回栈顶元素但不删除
