Module 1: Introduction & Setup

🌟 What is Java?

Java is a high-level, object-oriented programming language developed by Sun Microsystems (now owned by Oracle). It is platform-independent thanks to the Java Virtual Machine (JVM), which allows compiled Java code to run on any device that supports JVM.

💡 Features of Java

• Simple and easy to learn
• Object-Oriented
• Platform Independent
• Secure and Robust
• High Performance
• Multithreaded

⚙️ Setting Up Java

1. Download and install JDK from Oracle's website.
2. Install an IDE such as:
   • Eclipse
   • IntelliJ IDEA
3. Verify installation:

   java -version
                       javac -version

🚀 Your First Java Program

                    public class HelloWorld {
                        public static void main(String[] args) {
                            System.out.println("Hello, Java!");
                        }
                    }

Save the file as HelloWorld.java, compile with javac HelloWorld.java and run with java HelloWorld.
