Java implements

many different features and concepts, including:

1. Object-oriented programming: Java is an object-oriented programming language, which means that it provides support for creating and using objects.

2. Garbage collection: Java automatically manages memory allocation and deallocation through a process known as garbage collection.

3. Platform-independent: Java is platform-independent, meaning that it can run on any platform that has a Java Virtual Machine (JVM) installed.

4. Multithreading: Java provides support for multithreading, which allows multiple threads of execution to run concurrently within a program.

5. Exception handling: Java provides a robust exception handling mechanism that allows programmers to handle errors and exceptions in a structured and controlled way.

6. Generics: Java uses generics to provide type safety and overcome the limitations of using raw types.

7. Annotations: Java provides support for annotations, which allow programmers to add metadata to code and provide additional information to the compiler.

8. Reflection: Java allows programmers to inspect and modify the behavior of objects and classes at runtime through a feature called reflection.

9. Lambda expressions: Java 8 introduced lambda expressions, which provide a concise and expressive way to write code using functional programming concepts.

10. Streams: Java 8 also introduced streams, which provide a powerful and efficient way to process collections of data.
