Java, turning 30, remains a widely used programming language prioritizing stability and backward compatibility.Introduced in 1995 by Sun Microsystems with the concept of 'write once, run anywhere.'Java's success is attributed to its Java Virtual Machine (JVM) enabling platform independence.The language's continuous relevance is reflected in its utility, longevity, and adaptability.Java's emphasis on backward compatibility and smooth portability contributed to its success.Java's cautious evolution includes late additions like lambda expressions and gradual feature enhancements.Java's role in enterprise systems is strengthened by its compatibility and minimal need for code rewriting.Java's evolution from Java 2 to the recent Java 17 LTS release demonstrates modernization and adaptability.Java's compatibility with cloud computing, Java in the cloud, and its ventures into machine learning showcase its continued relevance.Projects like GraalVM and Panama expand Java's capabilities in cloud-native applications, machine learning, and high-performance computing.
