Jack's eyes lit up. "Ah, you're a Java fan, eh? Well, let me tell you, the latest Java version is Java 20, released in March 2023. But I think you're referring to the long-term support (LTS) version, which is Java 17, released in September 2021."
As of May 2026, the , which reached General Availability on March 17, 2026 . While Java 26 represents the bleeding edge of the platform’s development, enterprise users typically look toward Java 25 , the latest Long-Term Support (LTS) release launched in September 2025.
Jack pulled out a tablet and started showing Alex the features of the latest Java versions. "Java 17 introduced the Apple M1 chip support, improved security features, and enhanced performance. And Java 20, being a non-LTS version, brought in some exciting features like the incubating API for Java API for WebSocket, improved pattern matching, and enhanced performance."
Alex left the café feeling inspired and excited about the future of Java. She couldn't wait to dive into the new features and start building innovative applications with the latest Java versions.
As of , the most current Long-Term Support (LTS) version of Java is Java 21 .
If one defines "most current" as the absolute newest build available to the public, then the answer is a specific version number that advances every six months. As of mid-2024, that version is , released in March 2024. Following the pattern, Java 23 is expected in September 2024. This is the version where innovation is most visible. Java 22 continues the project’s modern evolution, delivering features like unnamed variables & patterns (to simplify lambda expressions), a foreign function & memory API (to safely replace the risky JNI), and improvements to the Stream API. For hobbyists, educators, and open-source contributors, Java 22 represents the cutting edge—a chance to see where the language is heading.
Java 21 is a truly monumental release, arguably the most significant since Java 8. It brings into general availability several "preview" features that have been in development for years. Virtual Threads (Project Loom) revolutionize server-side concurrency by allowing Java to handle millions of threads efficiently. Record Patterns and Pattern Matching for switch enable more expressive and safer data processing. Sequenced Collections add new interfaces for ordered data structures. For a production system that must be stable, secure, and maintainable, Java 21 is not just the most current option—it is the correct one. A company using Java 21 today is on the state-of-the-art for enterprise reliability.
As Alex sipped her coffee, she felt grateful for the chance encounter with Jack. She realized that Java was still a vibrant and dynamic language, with a strong community and a bright future.
Note: The next scheduled release is Java 24, expected in March 2025.
