About Java 21
Java 21 was released in September 2023 by Oracle as part of their regular update cycle for the Java programming language. It aimed to provide developers with long-term support and introduced significant features to enhance performance, security, and developer productivity. The release continued Java's tradition of evolving to meet modern development needs while maintaining backward compatibility.
Strengths of Java 21 include long-term support, improved performance, enhanced language features, and a robust ecosystem. Weaknesses may involve slower startup times compared to some newer languages and a larger memory footprint. Competitors include Python, C#, Kotlin, and JavaScript.
