GETTING STARTED WITH PYTHON

In this challenge, you will take your first steps in Python programming. Follow the steps below to set up your Python environment, create a simple Python script, and print "Hello, World!" to the console.

Step 1: Install Python

Go to the official Python website: https://www.python.org/downloads/
Download the latest version of Python (for Windows, macOS, or Linux) suitable for your operating system.
Run the installer and follow the installation instructions. Make sure to check the box that says "Add Python X.Y to PATH" (where X.Y is the version number).

Step 2: Open IDLE (Python's Integrated Development and Learning Environment)

Search for "IDLE" or "Python IDLE" in your computer's search bar and open the IDLE application.

Step 3: Create a Python Script

In IDLE, click on "File" in the menu bar and select "New File." This will open a new text editor window.
In the text editor, type the following Python code:
print("Hello, World!")

Step 4: Save the Python Script

Click on "File" in the menu bar and select "Save."
Choose a location on your computer to save the file. Make sure to navigate to a folder where you have write permissions.
Give your file a name with the ".py" extension (e.g., "hello_world.py"). The ".py" extension indicates that it's a Python script.

Step 5: Run the Python Script

In the text editor, click on "Run" in the menu bar and select "Run Module" or simply press the F5 key.
The Python script will execute, and you should see the output "Hello, World!" printed in the IDLE console.

Challenge Completion
Congratulations! You've successfully completed this coding challenge by installing Python, using IDLE, creating a Python script, and printing "Hello, World!" to the console. You're now on your way to becoming a Python programmer.

Feel free to explore further and modify the code to print different messages or perform other simple tasks. Happy coding!

GETTING STARTED WITH JAVASCRIPT

In this challenge, you will take your first steps in JavaScript programming. Follow the steps below to set up your JavaScript development environment, create an HTML file, add JavaScript code, and display "Hello, World!" in a web browser.

Step 1: Set Up Your Development Environment

If you don't already have a text editor or code editor installed, you can use a simple one like Notepad (for Windows) or TextEdit (for macOS) to write your code.

Step 2: Create an HTML File

Open your text editor and create a new file.
Type the following HTML code into your file:

<!DOCTYPE html>
<html>
<head>
<title>Hello, World!</title>
</head>
<body>
<h1>Hello, World!</h1>
</body>
</html>

Save this file with a ".html" extension (e.g., "index.html"). Make sure to choose a location on your computer where you have write permissions.

Step 3: Add JavaScript Code

Inside the <body> tag of your HTML file, add the following JavaScript code between <script> tags:

Inside the <script> tags, add the following JavaScript code to display "Hello, World!" in a pop-up alert:

alert("Hello, World!");

Step 4: Open the HTML File in a Web Browser

Locate the HTML file you created ("index.html") and double-click on it to open it in your default web browser.
You should see a pop-up alert with the message "Hello, World!" displayed in your web browser.

Challenge Completion
Congratulations! You've successfully completed this coding challenge by setting up a JavaScript development environment, creating an HTML file, adding JavaScript code, and displaying "Hello, World!" in a web browser. You're now on your way to becoming a JavaScript programmer.

GETTING STARTED WITH JAVA

In this challenge, you will take your first steps in Java programming. Follow the steps below to set up your Java development environment, create a Java class, compile it, and run a "Hello, World!" program.

Step 1: Install Java Development Kit (JDK)

Go to the official Oracle JDK download page: https://www.oracle.com/java/technologies/javase-downloads.html
Download the latest version of the Oracle JDK (Java Development Kit) suitable for your operating system (Windows, macOS, or Linux).
Install the JDK by running the installer and following the installation instructions.

Step 2: Set Up Your Text Editor or Integrated Development Environment (IDE)

You can use a simple text editor like Notepad (for Windows) or a more advanced code editor or IDE like Visual Studio Code, Eclipse, or IntelliJ IDEA.
If you choose to use an IDE, make sure to install it and set it up according to its documentation.

Step 3: Create a Java Class

Open your text editor or IDE.
Create a new Java class with the following code:

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

Step 4: Save and Compile the Java Class

Save the Java file with the same name as the class name and a ".java" extension (e.g., "HelloWorld.java"). Make sure to choose a location on your computer where you have write permissions.
Open your command prompt or terminal.
Navigate to the directory where you saved the Java file using the cd command (e.g., cd path/to/your/directory).
Compile the Java program by entering the following command:

javac HelloWorld.java

If there are no errors, a new file called "HelloWorld.class" should be generated in the same directory.

Step 5: Run the Java Program

In the command prompt or terminal, enter the following command to run the Java program:

java HelloWorld

You should see the output "Hello, World!" printed to the console.

Challenge Completion
Congratulations! You've successfully completed this coding challenge by setting up a Java development environment, creating a Java class, compiling it, and running a "Hello, World!" program. You're now on your way to becoming a Java programmer.
