Java shows the usage of External table-external list

Import java. util. Collections list;
Import java. util. vector;

/**
* Sun has already completed the orders table in Java. We only need to use the orders.
* When there are no requirements, you don't have to implement it yourself.
* If you need to implement it on your own, you can also implement it on your own.
* Similar to the previous list, the current interface method can be implemented in the same way.
* This is a simple example. If you are looking at your own response, you can go to this:

// Add the prefix vector to the specified position of the pre-increment table

// Remove the first
Head. Remove (head. getfirst ());
System. Out. println (head );
// Remove the first one and use the lower-level method. The lower-level starts from 0.
Head. Remove (0 );

}

The results are as follows:

[Puppies, USA, Xiaoyu, and Japan!]
[Puppy, USA, Xiaoyao, Japan !, Big Dog, laomei, Japan, laomiao]
