#### 示例

```java
import java.util.LinkedList;
class LinkedListClone {

  public static void main(String[] args) {

     // create a LinkedList
     LinkedList<String> list = new LinkedList<String>();

     // Adding elements to the LinkedList
     list.add("Element1");
     list.add("Element2");
     list.add("Element3");
     list.add("Element4");

     // Displaying LinkedList elements
     System.out.println("LinkedList elements: "+list);

     // Creating another list
     LinkedList<String> list2 = new LinkedList<String>();

     // Clone list to list2
     /* public Object clone(): Returns a shallow copy of this
      * LinkedList. (The elements themselves are not cloned.)
      */
     list2 = (LinkedList)list.clone();

     // Displaying elements of second LinkedList
     System.out.println("List 2 Elements: "+list2);
  }
}
```

**输出：**

```java
LinkedList elements: [Element1, Element2, Element3, Element4]
List 2 Elements: [Element1, Element2, Element3, Element4]
```
