Hello World in Multiple Languages Extravaganza: JAVA

Hello world project extravaganza, the java version.

Synopsis

This repository contains a collection of “Hello World” programs written in Java; from the simplest “Hello World” program in Java to a “Hello World” program in Java that uses the Model-View-Controller (MVC) pattern. This is part of a fun and educational project that showcases how to print “Hello World” in different programming languages. The goal is to have a “Hello World” program in every programming language. This project is inspired by the GitHub Hello World project and you can found it in Hello World Extravaganza website.

To get started, clone this repository to your local machine:

git clone https://github.com/silviotorre/helloworld.git

Getting Started

To run the “Hello World” program navigate to the project directory and run the program. Follow the instructions below to run the “Hello World” program in Java.

• Make sure you have Java installed on your computer. You can check if Java is installed by opening a terminal or command prompt and typing java -version.
• go in the java directory of hello world project and then compile the program by opening a terminal or command prompt, navigating to the directory where you saved the HelloWorld.java file, and typing javac HelloWorld.java. This will create a new file called HelloWorld.class.
• Run the program by typing java HelloWorld. This should output Hello, World! to the terminal or command prompt.

java HelloWorld

An advanced “Hello World” program in Java

In the MVC implementation, each class is defined in a separate file for better organization and readability. The Main class creates instances of the model, view, and controller, and then updates the model and view by calling the setMessage and updateView methods on the controller. The HelloWorldModel class represents the data and business logic, the HelloWorldView class represents the user interface, and the HelloWorldController class acts as a mediator between the model and view.

• There is four separate files in your project directory with the names HelloWorldModel.java, HelloWorldView.java, HelloWorldController.java, and Main.java.
• Compile the files using the command javac *.java in your terminal or command prompt
• Run the program using the command java Main in your terminal or command prompt.
• The output should be Hello, Java!.
