1.Simple Syntax

Java syntax is very straightforward and very easy to learn. Java removes complex features like pointers and multiple inheritance, which makes it a good choice for beginners.

2.Object-Oriented

Java follows Object-Oriented Programming (OOP) principles. Everything is treated as an object, which makes the code modular, reusable, and maintainable. Key OOP concepts in Java include Encapsulation, Inheritance, Polymorphism, and Abstraction

3. Platform Independent

Java follows the principle “Write Once, Run Anywhere” (WORA).
Compiled Java code becomes bytecode, which can run on any operating system with a Java Virtual Machine (JVM), making it highly portable

4.Interpreted

Java code is not directly executed by the computer. It is first compiled into bytecode. This byte code is then understand by the JVM. This enables Java to run on any platform without rewriting code.

5.Scalable
Java can handle both small and large-scale applications. Java provides features like multithreading and distributed computing.
It allows developers to add more features or handle more users without changing the core architecture.

6.Portable

• Java Programs can run on any platform without modification.
• After compilation, Java produces bytecode (.class files) instead of machine-specific code.
• The Java Virtual Machine (JVM) on any system can execute this bytecode, making Java programs highly portable across different operating systems like Windows, macOS, or Linux

7.Secured and Robust

• Java is secure because it prevents unauthorized access and ensures safe execution, and it is robust because it handles errors efficiently and manages memory automatically

8. Memory Management

• Java provides automatic memory management, which makes programs more reliable and reduces memory leaks.
• It has a Garbage Collector (GC) that automatically removes unused objects from memory.
• Makes applications more robust and efficient.

9. High Performance

• Java provides high performance because the JIT compiler converts bytecode into native code at runtime, and its memory and thread management optimize execution speed.

10. Multithreading

• Java supports multithreading, which means it can run multiple tasks simultaneously within a single program.
• Each thread runs independently, allowing better CPU utilization and faster execution.
• Useful in applications like animations, gaming, file downloads, and handling multiple user requests in web servers.
• Java provides built-in support for multithreading through the Thread class and Runnable interface.

11. Rich Standard Library

• Java provides various pre-built tools and libraries which is known as Java API.
• These libraries cover areas like data structures, networking, file I/O, database access, utilities, GUI,database connectivity (JDBC)
• and more.
• Developers can reuse pre-written code, which speeds up development and reduces errors.
• Popular packages include java.lang, java.util, java.io, java.net, and javax.swing.

12. Functional Programming Features

• Java supports functional programming concepts starting from Java 8, making code more concise and readable.
• Features include lambda expressions, streams, and functional interfaces.
• These allow developers to write declarative code, perform operations on collections easily, and enable parallel processing.
• Functional programming helps in reducing boilerplate code and improves productivity

13. Documentation and Community Support

• Java has extensive documentation and a large global community, which makes learning and problem-solving much easier.
• The official Java API documentation provides detailed explanations of classes, methods, and packages.
• A strong developer community contributes tutorials, libraries, frameworks, and answers on platforms like Stack Overflow, GitHub, and forums.
• This support helps developers quickly resolve issues, stay updated, and adopt best practices.
