The main functions and characteristics of the core framework in the Java class library

The core framework in the Java class library is an important part of the Java programming language, which provides many common functions and characteristics.The main functions include but are not limited to: 1. Collection framework: provides class and interfaces for storing and operating collection objects (such as lists, sets, mapping, etc.), including various data structures and algorithms, such as ArrayList, LinkedList, HashSet, Hashmap, etc. 2. Input output framework: including the File class and related input output streams, for file operation and data flow input output. 3. Network programming: Provides the socket class and related network communication categories for creating network connection and network communication. 4. Multi -threaded support: Provide a thread class and related synchronization and lock mechanisms for achieve multi -threaded programming and concurrent control. 5. GUI Framework: Provides graphic user interface libraries such as Swing and AWT to create and manage graphical user interface applications. The characteristics of the core framework in the Java class library include, but not limited to: 1. Object -oriented: The core framework in the Java class library is object -oriented. It uses object -oriented programming ideas and design principles to provide rich class and interfaces to support object -oriented programming styles. 2. Platform irrelevant: The core framework in the Java class library is not related to the platform and can run on different operating systems and hardware platforms, which makes the Java program have good transplantation and cross -platform. 3. Openness and scalability: The core framework in the Java class library is open. It can be expanded and customized by inheritance and interface implementation to meet the needs of different applications. 4. reliability and robustness: The core framework in the Java class library has been strictly tested and verified, with high reliability and robustness, and can support the development and operation of various applications. By using the core framework in the Java library, developers can build a reliable, efficient, and cross -platform Java application more quickly, and can make full use of the advantages and characteristics of the Java language.In the daily Java programming work, developers only need to simply call the class and interface provided by the core framework in the Java class library, which can achieve various common functions and greatly improve the maintenance of development efficiency and procedures.
