linkedListAPI

# 简介

- 父类

- java.lang.Object

- - java.util.AbstractCollection

- - java.util.AbstractList

- - java.util.AbstractSequentialList

- - java.util.LinkedList

- 实现的接口

```java

List, Deque, Cloneable, java.io.Serializable

```

# 属性

- size: 记录元素个数

- Node first: 双向链表头节点

- Node last: 双向链表尾节点

# 构造方法

- LinkedList() 构造一个空列表。

```java

/**

* Constructs an empty list.

*/

public LinkedList() {

}

```

- LinkedList(Collection<? extends E> c) 构造一个包含指定集合的元素的列表，按照它们由集合的迭代器返回的顺序。

```java

/**

* Constructs a list containing the elements of the specified

* collection, in the order they are returned by the collection's

* iterator.

*

* @param c the collection whose elements are to be placed into this list

* @throws NullPointerException if the specified collection is null

*/

public LinkedList(Collection<? extends E> c) {

this();

addAll(c);

}

```
