This week we have analyzed the previous procedures and learned the contents of the Nineth chapter of the collection.

The next step is to strengthen the review of the knowledge we have learned, and it is also an adjustment to deepen

The process.

We mainly master vector, Stack, Hashtable three classes, in the learning process more

In-depth mastery of the ArrayList class. ArrayList implements an array that is variable in size and

Can be accessed like a linked list. It provides functionality similar to the vector class but is out of sync with the array

Way to implement the list, allowing fast random access .

LinkedList implements a list that is suitable for inserting and removing elements. The linked list defined by this class is also

Can be used as a stack or as a queue.

Through the learning and mastering of various classes, the collection has a further understanding, the collection is a kind of containing

Multiple elements and provides an interface to the action methods of the contained elements, which can contain elements from the same class

Types of objects, or they can be made up of different type objects. In the next review session, you can enter a

It is a great promotion to be familiar with and master the content of the learning.
