4. Brick Breaker Game

This brick breaker game is one of many fun Java projects that has you trying to break bricks at the top of the screen. The player controls a tiny ball placed on a small platform at the bottom of the screen, which can be moved around from left to right using the arrow keys. The goal is to break the bricks without missing the ball with your platform. The project makes use of Java swing and OOPS concepts, among other things.

How To Setup Your Java Environment

Before you start coding in Java, it's essential to have your coding environment properly set up and ready for action.

Being a compiled language that runs on a wide range of devices through the Java Virtual Machine (JVM), Java requires a bit more setup compared to interpreted languages like JavaScript that run directly in web browsers.

Here's how to set up a Java development environment on most operating systems.

Install a Java Development Kit (JDK)

First and foremost, you need the JDK, which includes the Java Runtime Environment (JRE) and the compilers and tools needed to compile and run Java applications.

  • Download the JDK: Visit AdoptOpenJDK or Oracle's official Java site to download the JDK. I recommend choosing the LTS (Long-Term Support) version for stability.
  • Install the JDK: Run the installer and follow the instructions. Make sure to set the JAVA_HOME environment variable to the JDK installation path and add the JDK's bin directory to your system's PATH. This is crucial for making Java commands accessible from your command line or terminal.

Verify Installation

After setting up, verify that everything is working correctly.

To begin, open a terminal or command prompt and run these commands to check the installed Java and Java compiler versions, respectively:

java -version
javac -version

Then, try creating a simple Java program and compile it using:


Then run it with:

java YourProgram

This should confirm your JDK is correctly set up.

Install a Java IDE or Code Editor

You'll need an IDE or code editor that supports Java syntax highlighting and potentially IntelliSense for code completion.

Eclipse, NetBeans, and IntelliJ IDEA are some of the most popular choices and three of my personal favorites.

That said, I'd also consider Visual Studio Code (VSCode) as this is a hugely popular choice among developers for various languages thanks to its extensive and lightweight feature set and vast library of extensions.

If you do go the VSCode route, head to the VSCode extension marketplace and install the ‘Extension Pack for Java’ from Microsoft, and you’ll be good to go.

If you're really new to coding, you might want to skip this step, but even then, I'd really recommend becoming familiar with Git as soon as you can.

If you want the TL-DR, Git is a version control system that lets you track changes in your code and collaborate with others.

While this step is not strictly necessary for Java development, it's a best practice, especially for larger projects or when working in a team.

Simply download Git from the official Git website, and during installation, you can accept most default settings. That said, you might want to choose your preferred text editor and ensure that Git is added to your system's PATH.

Wrapping Up

And there we have it! If you've taken the time to build these 10 Java projects, you should be feeling much more competent and confident with Java.

You'll also have a burgeoning Java portfolio that's packed full of interesting and practical Java projects, each demonstrating your dedication and abilities.

I also hope you enjoyed following along with my step-by-step tutorial on the first three Java projects!

My motivation with these Java tutorials is to guide you through the nuances of Java development while also giving you hands-on experience that you'd usually only get when taking a Java course.

Here at, we're huge fans of project-based learning, so I hope these Java projects have bolstered your confidence and sparked a deeper interest in web development or any other form of Java development.

Remember, the journey doesn't end here!

With new projects and step-by-step tutorials regularly added to this page, be sure to check back often for new opportunities to refine your Java skills and expand your portfolio.

Happy coding!
