For developing new software systems, object-oriented programming is undoubtedly the most widely used programming model today. Due to the persistence requirements of commercial data, relational database management system (RDBMS) has been widely used. RDBMS uses a relational model, which is different from the domain object model in the software system. When developing software systems using object-oriented programming languages and using RDBMS to persistently store data, the data persistence
Java Collection Framework 1, overview: The collection framework is designed to meet several goals.
The framework must be high-performance. The implementation of the basic set (dynamic array, linked list, tree, hash table) must also be efficient.

I was so busy recently that I wrote last night that I fell asleep. Well, let's write the Java framework.Logs and certain monitoring in any system are very important. maintenance during the entire life cycle of a software is always a big headache at the same time, log and monitoring provides a good foundation and means for later maintenance. In Java projects, most log4j is used to record system logs. Almost
