All the collection-related implementation classes in Java are implementation classes for these six interfaces.Collection interface: Each element in the collection is an object, which organizes the objects together to form a one-dimensional structure.The list interface represents the organization of elements in a certain order of relevance (in which the order is p
Differences between abstract classes and interfaces
Abstract classes can contain non-abstract methods, and interfaces can only contain abstract methods.
Abstract classes cannot contain braces when declaring abstract methods, but all methods in the interface do not.Abstract class ):

In my first article, I am mainly using the Asp.net Mvc Framework + LinQ for development.
The following content involves the knowledge and generics of LinQ. If you have never understood it, search for related information in the blog garden. I will not introduce it here.
Assume that there is a user table in the database. (DEMO)
Create a LINQ to SQL class named testdata. dbml and drag the data table user. (Steps omitted)
Add a new class named tablemodel. The content is blank. Expand testdata. dbml,
