This chapter focuses on collections, starting with the Java Collection Framework, where the Java collection class accommodates only objects, and the objects that hold them are instances of object. Among them, the common collection class has vector (vector), stack (stacks), Hashtable (hash table) and so on. After the JDK1.2 version, there is the COLLECTION.LIST.SET.MAP. This week's collection is relatively simple and has a good effect over last week's generics programming. Set.map of these two classes is not very understanding, but I will go down to review hurriedly fill up.
