Contributing to a project is more than just sending code. Open source projects require many forms of contributions including (but not limited to) writing documentation, project management, testing, quality assurance, translating and identifying bugs. The author will provide eight tips to show you how to contribute your time and effort to the Java open source project .
This book is an attempt to answer the question ‘How do I get started contributing to Java open source project?’ It covers topics like, making a choice of a project, finding and downloading source files, setting up your development environment, commenting the code, writing tests and documentation. Other topics covered include, understanding the purpose of existing test cases, learning how to write new test cases, generating reports, creating issues and contributing more complex changes like fixing bugs and adding features.
Get to know GitHub
GitHub is the most popular platform for open source collaboration, so you’ll probably use it when exploring the world of OSS. First, you need to create a GitHub account and read the guide that helps you get started. On GitHub, you can contribute to projects by submitting issues and contributing code. Submitting issues means sending messages about errors in applications and suggesting ways to fix them. Contributing code involves sending pull requests with your corrections and improvements.
Java Design Patterns
Design patterns are among the most useful practices for a programmer. They help you speed up the programming process by solving general problems much quicker. Design patterns provide you with tested development paradigms, so the development process becomes quick and straightforward.
You can reuse design patterns to avoid small errors and issues, leading to significant problems in your project. Another advantage of design patterns is they enhance your code’s readability for others.
As the name suggests, Java design patterns is a collection of design patterns for Java. A product of seasoned architects and programmers, the patterns help you simplify development with Java. The project requires you to be familiar with the numerous Software Design Principles.
All the patterns in this project have useful descriptions to understand where you should use a particular pattern and where you shouldn’t. We recommend learning more about this project as it’s a must-have for every Java programmer. It has over 62 thousand stars on GitHub, so you can understand how popular it is.
Learn the basics
When working with GitHub, you should know how to use Git – one of the most popular version control tools (also known as revision control tools). Because developers constantly make changes to their code, they need a system that can manage those changes in a central repository. In this way, everyone involved in the development process can download a given piece of software, make changes, and submit updates.
If you’re interested in the Internet of Things (IoT), then you must get acquainted with Arduino. It is an open-source electronics platform based on simple software and hardware. An Arduino board can read various inputs such as a finger pressing a button, a tweet, or a light on a sensor and convert it into an output, such as turning on a torch, activating a system, or publishing something.
As a microcontroller platform, it’s very accessible and easy to use. It has cross-platform compatibility as it can run on Mac OSX, Windows, and Linux. Even though it is quite simple to use, its versatility and flexibility make it suitable for experienced programmers.
If you want to use Java in IoT, then learning about Arduino would surely be a significant step. Its GitHub repository has more than ten thousand stars, so you can understand how popular it is.
Sndcpy is a neat solution for android audio forwarding. You can say that it’s scrcpy but for Android. Scrcpy is an open-source application for screen mirroring that lets you control an Android device from a macOS, Windows, or Linux desktop computer. Sndcpy enables you to forward audio from an Android ten device to your computer without needing any root access.
It is compatible with Windows, macOS, and Linux operating systems. As it is written in Java, you can learn a lot about it through its source code. Sndcpy is one of the best Java open source project ideas as you can try to replicate this solution and learn a lot about Java mobile development.
Join the community
You can easily join an open source project by subscribing to the mailing list for that project. You can find mailing lists on official websites or on GitHub pages. After being accepted to the list, you can communicate with team members and get support if necessary. Thanks to the vibrant communities present in nearly every OSS project, you are likely to get quick replies to your questions.
Termux is a terminal emulator for Android. A big reason behind its immense popularity is its extensive collection of Linux packages. It lets you edit files with vim and nano, connect to servers over ssh, use the Python console as a calculator, or use frotz to run text-based games.
Learning about this project can teach you a lot about terminal emulation and Java mobile development. You can understand how popular it is when you consider that it has more than 6.7 thousand stars on its GitHub page.
All skills are welcomed
Even non-programmers can contribute to open source projects! Documentation is needed for all projects, and sometimes this is poorly written and maintained. Thus, you can help by writing, updating or even translating documentation. Also, your design skills might come in handy: every application needs an interface, after all. Finally, you can contribute by managing a community by replying to questions and guiding newcomers.
If you’re interested in gaming and video game development, then this project is perfect for you. Mindustry is a resource management strategy game written in Java. You can check its code and see how the game works. It has more than six thousand stars on Github, so you can understand how popular it has become. If you want to learn about video game programming, getting familiar with this project will surely help.
Nowadays, almost each and every one of us uses some open source libraries and frameworks in our software development. They make our life easier by providing useful functionality like graphics, data structures and more.
