Welcome to the first article of Java for DSA series! Before diving into algorithms and data structures, it’s essential to understand the language and environment we’ll be working with.

Features of Java

✅ Simple & Portable – Easy to learn and write, and runs across different platforms.

🧱 Object-Oriented – Everything is modeled as objects.

🌐 Platform Independent – Write Once, Run Anywhere (WORA).

🔐 Secure & Dynamic – Features like bytecode verification and dynamic linking.

⚡ High Performance – Thanks to the Just-In-Time (JIT) compiler.

🛡️ Robust – Automatic garbage collection and strong memory management.

🔁 Multithreaded – Supports concurrent execution for better performance.

Structure of Program

class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!"); 
    }
}
// compiling - javac test.java
// running - java test
