➡️Why Learn Java?

Java is one of the most popular programming languages used for web development, mobile applications (Android), enterprise software, and more. Learning Java sets a strong foundation for building robust applications.

 ➡️To Running a Java Program:-

📌Helps understand System.out.println() for output in Java.

📌First program to debug and troubleshoot syntax issues.

📌A great way to explore how Java works under the hood.

📌Java Hello World is the foundation for learning loops and logic.

📌It introduces the Java Development Kit (JDK) usage.

📌Hello World showcases Java’s platform independence.

📌Helps differentiate between compile-time and run-time errors.

1. Install Java Development Kit (JDK):

To run Java programs, you need to install the Java SE Development Kit (JDK). Follow these steps:

• Download the latest JDK version from the https://www.oracle.com/in/
• Install and set up environment variables for Java.

2.Choose a Text Editor or IDE:

You can write Java programs in any text editor like Notepad, VS Code, or IntelliJ IDEA. For beginners, Notepad or an online Java compiler is a simple choice.

3. Write Your First Java Program:

Copy and paste the following code into your editor:

java

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

4.Save and Compile the Java Program:

• Save the file as HelloWorld.java (file name must match the class name).
• Open the Command Prompt (cmd) and navigate to the folder where the file is saved.
• Compile the program using:

nginx

javac HelloWorld.java

• If there are no errors, a HelloWorld.class file will be created.

5. Run the Java Program:

To execute the program, type:

nginx

java Hello World

You will see the output:

Hello, World!

➡️Understanding Java Command Line Arguments:-

• Essential for grasping basic Java file structure and naming conventions.
• Boosts confidence for beginners starting with Java.
• Java Hello World is often the first interview coding question.
• Easy to understand for students and self-learners alike.
• Acts as a gateway to learning Java classes and objects.
• Can be enhanced with comments to understand code flow.

Java allows passing arguments to programs via the command line. Example:

java

class Demo {
    public static void main(String args[]) {
        System.out.println("Argument 1 = " + args[0]);
        System.out.println("Argument 2 = " + args[1]);
    }
}

Run the program using:

• Hello World teaches how to save and run .java files.
• Simple yet powerful—Java Hello World marks the start of your coding journey.

mathematica

java Demo Apple Orange

Output:

mathematica

Argument 1 = Apple  
Argument 2 = Orange  

➡️Best Practices for Java Beginners:

✅ Always save your file with the .java extension.
✅ Java is case-sensitive, so be consistent in naming conventions.
✅ Use an IDE like Eclipse or IntelliJ IDEA for faster development.

➡️Final Thoughts:-

Java is a versatile language widely used in software development. Mastering basic syntax, compiling, and running programs is the first step toward becoming a proficient Java developer.
