What are the main differences between Java 8 and Java 11 in terms of features and capabilities?

The main differences between Java 8 and Java 11 include:

1. Support and updates: Java 8 is a long-term support (LTS) version, while Java 11 is the next LTS version with more modern improvements.

2. Removed modules: In Java 11, some deprecated modules, such as Java EE and CORBA modules, which were available in Java 8, have been removed.

3. New APIs and improvements:

   • Java 11 introduces new methods for working with strings (isBlank(), lines(), strip(), etc.).
   • Improved handling of collections and streams.

4. Support for new language features: Java 11 does not add major syntactic changes but includes performance and security enhancements.

5. Tools: Java 11 introduced a new tool java for running .java files without prior compilation.

6. Garbage Collector: Java 11 improved garbage collector performance, with experimental support for ZGC.

Thus, Java 11 is a more modern version with improvements in performance, security, and development convenience, but it also removes some deprecated components present in Java 8.
