这就是列表中的指针在内部看起来如何add其实际add到列表中，您需要这样做：

List<String> s = new LinkedList<>(); 

s.add("a"); 
s.add("b");
s.add("c");
s.add("d");

Take a look at this answer.

LinkedList<String> list = new LinkedList<>();
list.add("a");
list.add("b");
list.add("c");
list.add("d");

If you really want it on one line:

LinkedList<String> list = new LinkedList<>(Arrays.asList("a","b","c","d"));

Though that does have a performance overhead.

你可以这样做：

LinkedList<String> linkedList = new LinkedList<String>();
    linkedList.add("a");
    linkedList.add("b");
    linkedList.add("c");
    linkedList.add("d");
