Request Collections: Below is a table of the Request collections and descriptions to how they are used.

InheritanceWhen defining a new class, "Object" is usually written in parentheses, which is actually the class that the definition inherits from. So the class written in parentheses is the class to which the defined class inherits. The inherited class can be either a

, non-synchronous, and delete the speed quicklyAPI documentation explains: The list interface is implemented as a link listing. Implements all optional list operations, and allows all elements (including null). In addition to implementing the list interface, theLinkedList class provides a uniform naming method for the get,remove , and insert elements at the beginning and end of the list. These operations allow the link list to be used as a stack, queue, or double-ended queue.Java Learning

① when a virtual function is declared in a class, the compiler generates a virtual function table in the class that is a data structure that stores the address of the member function (virtual function).The ② virtual function table is automatically generated and maintained by the compiler.The ③ virtual member function is placed into the virtual function table .④ There is a virtual function, Each object has a pointer to the virtual function tableAnalys

Like an array, it includes components that can be interviewed using an integer index. However, Vector the size can be scaled up or down to suit the Vector action of adding or removing items after creation.2.ArrayList:
