方法详细资料

push

public E push(E item)

从接口复制的说明: Stack

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

 addElement(item)

指定者:

push 在接口中 Stack<E>

参数:

item - the item to be pushed onto this stack.

返回:

the item argument.

另请参阅:

Vector.addElement(E)

pop

public E pop()

从接口复制的说明: Stack

Removes the object at the top of this stack and returns that object as the value of this function.

指定者:

pop 在接口中 Stack<E>

返回:

The object at the top of this stack (the last item of the Vector object).

peek

public E peek()

从接口复制的说明: Stack

Looks at the object at the top of this stack without removing it from the stack.

指定者:

peek 在接口中 Stack<E>

返回:

the object at the top of this stack (the last item of the Vector object).

search

public int search(Object o)

从接口复制的说明: Stack

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.

指定者:

search 在接口中 Stack<E>

参数:

o - the desired object.

返回:

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.

size

public int size()

指定者:

size 在接口中 Collection<E>

isEmpty

public boolean isEmpty()

指定者:

isEmpty 在接口中 Collection<E>

contains

public boolean contains(Object o)

指定者:

contains 在接口中 Collection<E>

iterator

toArray

public Object[] toArray()

指定者:

toArray 在接口中 Collection<E>

toArray

public <T> T[] toArray(T[] a)

指定者:

toArray 在接口中 Collection<E>

add

removeAll

public boolean removeAll(Collection<?> c)

指定者:

removeAll 在接口中 Collection<E>

retainAll

public boolean retainAll(Collection<?> c)

指定者:

retainAll 在接口中 Collection<E>

clear

public void clear()

指定者:

clear 在接口中 Collection<E>
