Difference Between Java 8 And Java 11
Java 8 and Java 11 are both versions of the Java programming language, with Java 8 being released in 2014 and Java 11 in 2018. Java 8 introduced significant features such as lambda expressions, the Stream API, and the Optional class, which aimed to improve code readability and performance. On the other hand, Java 11 focused more on enhancing the platform by introducing features like local-variable syntax for lambda parameters, HTTP client API, and enabling the use of newer versions of Java features through modules. Additionally, Java 11 also marked the end of public updates for Java 8, making it essential for users to upgrade to newer versions for continued support and security updates.

1 - Introduction of Modular System: Java 9 introduced the concept of modules, allowing developers to create more efficient and scalable applications by breaking down the code into smaller modules. This helps in managing dependencies and improving performance.
2) Enhanced Security: Java 11 includes updates to security features such as TLS 1.3, key agreement with Curve25519 and Curve448, and improved security protocols. This ensures better protection against security threats.
3) JEP 321 HTTP Client API: Java 11 introduced a new HTTP Client API as a replacement for the legacy HttpURLConnection API. This new API provides a more flexible and efficient way to handle HTTP requests and responses.
4) JEP 328 Flight Recorder: Java 11 introduced Flight Recorder, which was previously a commercial feature in Java Mission Control. This tool helps developers to monitor and diagnose applications in real time, providing valuable insights into application performance.
5) Local Variable Syntax for Lambda Parameters: Java 11 introduced the ‘var’ keyword for lambda parameters, allowing developers to declare variables without explicitly specifying their data types. This enhances code readability and reduces verbosity.
6) Epsilon Garbage Collector: Java 11 introduced the Epsilon Garbage Collector, a low overhead, no op garbage collector designed for performance testing and zero allocation scenarios. This collector can be useful for specific use cases where garbage collection is not required.
7) Java Flight Recorder Event Streaming: With Java 11, developers can now stream Java Flight Recorder events in real time, enabling better monitoring and analysis of application behavior. This feature enhances performance tuning and troubleshooting capabilities.
8) Improved Unicode Support: Java 11 added support for Unicode 10. This means that developers can work with the latest Unicode standards and benefit from new characters and emojis in their applications.
These are just a few of the key differences between Java 8 and Java 11 that students should be aware of when transitioning to the newer version.
