Hour of Code: Top 5 Java Projects

Ekaterina Khudikova

It’s the second day of the Hour of Code celebration, and we’re back with more amazing projects to tell you about! Today’s topic is Java, and in case you missed our post about the TOP-5 most popular Python projects on JetBrains Academy, you can still catch up.

Java is a true leviathan of the programming world. Since its launch in 1995, it continues to stay relevant to this day. Java is a versatile programming language that is equally used in software, web, and mobile application development. Java is a strong general-purpose language because of its ability to run on a cross-platform Java Virtual Machine (JVM). And even though some of the newer languages are also relatively platform-independent, Java still stands as the golden standard for programming languages that let you run the same code almost anywhere. 

With all that in mind, it comes as no surprise that Java is the most popular learning language on JetBrains Academy. So, we are pretty confident that the following projects are the best ones to include in your Java learning journey.

💬 Simple Chatty Bot (Easy)

Don’t be surprised if you see this project mentioned a lot in our posts. Simple Chatty Bot is a timeless classic on JetBrains Academy, which found its way to practically every single track we have. And what can be better than your own chatty companion? You will be able to play word and number games together and even teach your bot to quiz you on different topics. With this project, you will learn the basics of Java syntax and get familiar with variables, conditions, loops, and methods.

☕️ Coffee Machine (Hard)

There’s nothing greater than a cup of hot coffee during a break. Even better if it’s just one button of the coffee machine away. With this project, you will program your own coffee machine! You will be able to select the desired amount of milk and sugar and order three different types of coffee: espresso, cappuccino, and latte. This project will help you better understand the basics of object-oriented programming (OOP), teach you how to work with classes, class methods, and attributes, and check your knowledge of loops and conditions.

🎦 Cinema Room Manager (Medium)

Cinema has been a major part of our lives for a long time: a movie is a great way to escape reality and live through a variety of emotions. With this project, you will create an application to manage a cinema theater. It will be able to sell tickets, check available seats, show statistics, and more. Cinema Room Manager will teach you to work with input and output, deal with arrays and functions, and operate loops and conditional statements.

🎬 Cinema Room REST Service (Hard)

While we are on the topic of cinema, here’s something for our more advanced learners. The next step after mastering the fundamentals of Java is usually learning how to work with its most popular framework – Spring Boot. In this project, you will create a simple Spring REST service to manage a small movie theater. You will learn to handle HTTP requests in controllers, create services, and respond with JSON objects.

⚓️ Battleship (Challenging)

If movies are not your cup of tea, what do you say about some naval battles? After all, writing games is probably one of the most exciting ways to learn programming. Battleships is a popular strategy game for two. Each player marks their ships on a special grid and then takes turns in guessing where the opponent’s ships are located. The first one to sink all the enemy ships wins. After completing the project, not only will you have a great way to pass time on your hands, but you will also understand the process of developing a complex program, get familiar with processing user input, and learn different ways to handle errors.
