Java Version 11

Java 11, also known as Java SE 11, is a long-term support (LTS) release of the Java Platform, Standard Edition (Java SE). . Some of the key features include:

1. Local Variable Type Inference (var): Java 11 introduced the ‘var’ keyword, which allows you to declare variables without explicitly specifying the type. The type is inferred from the context.

2. HTTP Client (Standard): A new HTTP client was introduced as a standard feature, providing a more modern and efficient way to make HTTP requests and handle responses.

3. Epsilon Garbage Collector: A new experimental garbage collector called Epsilon was added. It is designed for scenarios where you want to disable garbage collection completely or delay it indefinitely.

4. ZGC (Experimental): Java 11 introduced the Z Garbage Collector (ZGC) as an experimental feature. It is designed to provide low-latency and high-throughput garbage collection for large heaps.

5. Flight Recorder: The Flight Recorder, previously a commercial feature, became available in Java 11 as a part of OpenJDK. It allows continuous monitoring of the JVM and helps in analyzing performance and troubleshooting issues.

6. Nest-Based Access Control: Java 11 introduced the concept of nest-based access control, allowing classes in the same nest to access each other’s private members without the need for reflection.

7. Launch Single-File Source-Code Programs: With Java 11, you can directly run single-file source-code programs without the need for explicit compilation. The ‘java’ command can now be used to run .java files directly.

8. Unicode 10 Support: Java 11 added support for Unicode 10, which includes many new characters, emojis, and scripts.

Java 11 is an LTS release, meaning it is officially supported for an extended period (typically for several years) compared to non-LTS releases.
