      Throws:
      EmptyStackException - if stack is empty.

    • empty

      public boolean empty()
      Tests if stack is empty.
      Specified by:
      empty in interface Stack<T>
      Returns:
      true if the stack is empty; false otherwise.

    • size

      public int size()
      Returns the size of the stack.
      Specified by:
      size in interface Collection<T>
      Specified by:
      size in interface List<T>
      Specified by:

    • clear

      public void clear()
      Specified by:
      clear in interface Collection<T>
      Specified by:

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • equals

      public boolean equals(Object obj)
      Compares the specified object with this list for equality. Returns true if and only if the specified object is also a list, both lists have the same size, and all corresponding pairs of elements in the two lists are equal. (Two elements e1 and e2 are equal if (e1==null ? e2==null : e1.equals(e2)).) In other words, two lists are defined to be equal if they contain the same elements in the same order.

      This implementation first checks if the specified object is this list. If so, it returns true; if not, it checks if the specified object is a list. If not, it returns false; if so, it iterates over both lists, comparing corresponding pairs of elements. If any comparison returns false, this method returns false. If either iterator runs out of elements before the other it returns false (as the lists are of unequal length); otherwise it returns true when the iterations complete.

      Specified by:
      equals in interface Collection<T>
      Specified by:
      equals in interface List<T>
      Overrides:
      equals in class Object
      Parameters:
      obj - the object to be compared for equality with this list.
      Returns:
      true if the specified object is equal to this list.

    • hashCode

      public int hashCode()
      Returns the hash code value for this list.

      This implementation uses exactly the code that is used to define the list hash function in the documentation for the List.hashCode method.

      Specified by:
      hashCode in interface Collection<T>
      Specified by:
      hashCode in interface List<T>
      Overrides:
      hashCode in class Object
      Returns:
      the hash code value for this list.

    • search

      public int search(T 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.
