Khám phá

Java (OpenJDK) is one of the world's most popular programming languages, known for its 'write once, run anywhere' philosophy. Java is platform-independent, object-oriented, and battle-tested in enterprise environments for decades. With the Java Virtual Machine (JVM), code compiled to bytecode runs on any platform without modification. Java powers everything from Android apps to enterprise backend systems, big data processing (Hadoop, Spark), and web applications (Spring Boot). OpenJDK is the free, open-source implementation of the Java Platform, providing the same features as Oracle JDK with a GPL license.
