Difference between Java8 and Java 11


Java 8 and Java 11 are both major releases of the Java programming language, but there are several key differences between the two versions. Some of the main differences include:

1. Support: Java 8 is a long-term support (LTS) release, which means it will continue to receive updates and security patches until at least December 2020. Java 11, on the other hand, is a non-LTS release and only receives updates for 6 months after a new version is released.

2. Modules: Java 11 introduced the Java Platform Module System (JPMS), also known as "Modules", which is a major enhancement to the Java Platform. It makes the platform more scalable, secure and maintainable. Java 8 does not have this feature.

3.  String API Improvements: Java 11 includes several new methods in the String API, such as isBlank(), strip(), repeat(), and lines(), to make it easier to work with strings. Java 8 does not have these methods.

4. Local-Variable Type Inference: Java 11 introduced the ability to infer the type of a local variable from its initializer, using the "var" keyword. This feature can make code more concise and readable. Java 8 does not have this feature

5. HTTP Client: Java 11 includes a built-in HTTP client that replaces the previous HttpURLConnection API. This new client supports both synchronous and asynchronous programming models, and is designed to be more efficient and secure. Java 8 does not have this feature.

6. Deprecated Modules: Java 11 includes several deprecated modules that have been removed in Java 11, including JavaFX, JavaEE, and the Java browser plugin. Java 8 includes these modules.

7. Improved Garbage Collection: Java 11 includes improvements to the G1 garbage collector, which can lead to better performance and reduced pause times. Java 8 does not have this feature.

8. Removal of Java EE and CORBA Modules: Java 11 removes a number of Java EE and CORBA modules from the JDK, including Java EE, CORBA, and JAXB. Java 8 includes these modules.

9. Multi-Resolution Images: Java 11 includes support for multi-resolution images, which allows an application to automatically use the best resolution for a given device or display. Java 8 does not have this feature.

10. New Hashing Algorithms: Java 11 includes new cryptographic hashing algorithms, including SHA-3, which provides stronger security than the older SHA-1 and SHA-2 algorithms. Java 8 does not have this feature.

11. Improved Performance: Java 11 includes several performance improvements, such as a more efficient Just-in-time (JIT) compiler, which can lead to faster startup times and improved overall performance.

12. ZGC (Z Garbage Collector): Java 11 includes a new low-latency Garbage collector called ZGC which is designed for large-scale, heap-size applications.

Overall, Java 11 brings many new features, improvements, and better performance than Java 8.
