GNU/Linux CentOS 9 Stream Installing Oracle JDK 17 - QuickStart Guide Hello Linux user! The Tutorial shows you Step-by-Step How to Download and Install Oracle JDK 17 in CentOS 9 Stream 64-bit GNU/Linux. And Java SE 17 for CentOS 9 is a Development Environment for Building Applications, and Components Using the Java Programming Language. Here are some Key Points of JDK: Compiler and Tools: The JDK includes a Java compiler (javac) that translates Java source code into bytecode, which can be executed by the Java Virtual Machine (JVM). It also contains various tools for development, debugging, testing, and monitoring Java applications. Java Runtime Environment (JRE): In addition to the development tools, the JDK includes the Java Runtime Environment (JRE), which is necessary for running Java applications. The JRE consists of the JVM, class libraries, and other components required for executing Java bytecode. Java API Documentation: Oracle JDK provides comprehensive documentation for the Java API (Application Programming Interface). This documentation includes detailed descriptions of classes, interfaces, methods, and other elements of the Java standard library, making it a valuable resource for developers. Platform Support: Oracle JDK is available for multiple platforms, including Windows, macOS, and various Unix/Linux distributions. This allows developers to write Java applications that can run on a wide range of operating systems and hardware architectures. Security Features: Oracle JDK includes security features to help developers build secure Java applications. This includes support for cryptographic algorithms, secure communication protocols, and mechanisms for managing security policies and permissions. Performance Optimization: Oracle continuously works on improving the performance of the JDK, including the JVM and the Java runtime libraries. This ensures that Java applications run efficiently and can scale to meet the performance requirements of various use cases. Updates and Support: Oracle provides regular updates and patches for the JDK to address security vulnerabilities, bug fixes, and performance enhancements. Developers can also access technical support and resources through Oracle's website and community forums. Licensing: As of recent updates, Oracle has changed its licensing and support model for Oracle JDK. While Oracle JDK is still available for free for development and testing purposes, commercial use may require a subscription or licensing agreement. Alternatively, developers can use OpenJDK, which is an open-source implementation of the Java Platform, as an alternative to Oracle JDK.
