Key Features of Java:

1. Platform Independence:

   • Java code is compiled into bytecode that can run on any device equipped with the Java Virtual Machine (JVM). This ensures that Java programs are portable and can be executed across various environments without modification.

2. Object-Oriented:

   • Java is built around objects, making it easy to model real-world problems. Key principles include encapsulation, inheritance, and polymorphism.

3. Simple and Familiar:

   • Java's syntax is straightforward and easy to learn, especially for those familiar with C or C++.

4. Secure:

   • Java provides robust security features like runtime checking, bytecode verification, and a security manager to restrict what Java applications can do at runtime.

5. Multithreaded:

   • Java has built-in support for multithreading, allowing for concurrent execution of two or more threads for maximum utilization of CPU.

6. Robust and Reliable:

   • Java emphasizes early checking for possible errors, as well as runtime checking. The language's garbage collection feature helps in managing memory automatically.

7. High Performance:

   • While Java is not as fast as languages like C or C++, its performance is enhanced by Just-In-Time (JIT) compilers and the efficient management of memory.

8. Rich Standard Library:

   • Java comes with a large standard library that provides many functionalities, from data structures to networking to graphical user interface (GUI) development.
