About Java

Java is a popular, object-oriented programming language designed for portability across platforms ("write once, run anywhere").

Key features:

• Platform independence via the Java Virtual Machine (JVM)
• Strong typing and memory safety
• Rich standard library (collections, streams, concurrency, I/O, GUI, networking)
• Robust object-oriented design (classes, interfaces, inheritance, polymorphism, encapsulation)
• Automatic garbage collection

Repository structure

Files in this repo are numbered practice problems:

• Basic Java to Advance Java (example exercises and hands-on assignments)

Getting started

1. Install JDK (Java Development Kit) 17 or newer.
2. Open a terminal in this folder (Java-Tutorial).
3. Compile a program:
   • javac Main.java
4. Run the program:
   • java Main

Example Java program (main method)

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

Tips

• Use javac to compile and java to run.
• Use IDEs (IntelliJ IDEA, Eclipse, VS Code) for easier editing, compiling, and debugging.
• Keep each class in its own file (named ClassName.java) for larger projects.
