At the end of a Java course, I usually motivate my students with some of the best projects on GitHub. This article compiles the five most popular projects on GitHub in Java.
As you probably know, GitHub contains many programming projects, and there are approximately 744K projects in Java. In this post, I will describe some of GitHub’s repositories, from the well-known Mockito to Guava.
Mockito
Although its name sounds like a drink, Mockito is a popular Java unit test framework that constantly updates using the Ship kit library.
Mockito can be integrated with JUnit. It Allows you to create and configure mock objects and simplifies the development of tests for external library-dependent classes.
Mockito implements the tests by following steps:
- Avoid external dependencies and put mock objects in the code that will be tested.
- The code is executed in the unit test.
- Checking if the code is executed correctly.
Java-Design-Patterns
I haven’t often mentioned Java Design Patterns, but this project is right because it allows developers to implement design patterns in Java.
These design templates are best practices to help developers solve the most common problems while building a Java application. These design patterns will also speed up the Java application development process, enabling tested and proven development paradigms.
RxJava
You’ve heard of RxJava as one of the most popular applications on GitHub and a very popular framework for some time.
This project is based on ReactiveX API. RxJava is a library used to build asynchronous and event-based applications.
RxJava is an extension of the Observer model, which supports precisely the sequence of events and data. It also includes operators that allow the programmer to build sequences such as thread synchronization, the security of concurrent threads, and so on.
MPAndroidChart
MPAndroidChart is a library that allows you to create graphs in the development phase of Android applications running in API 8 or above. With MPAndroidChart, developers can build a series of graphs for Android apps, such as LineChart, BarChart (Vertical, Horizontal, Clustered), PieChart, ScatterChart, CandleStickChart (for financial data), RadarChart, BubbleChart, and CombinedChart.
Guava
Guava is a Google library for Java. It was created some years ago but is still a very popular, open-source tool widely used by Java programmers. Guava will save you a lot of time by providing the necessary classes and simplifying Java, especially in data structures like collections. Listing such structures will often be difficult, but the Guava functionalities will allow you to compare the contents of collections using the ComparisonChain function.
In conclusion, I recommend searching for additional details about these projects and searching GitHub for other popular Java repos. You can also read some suggested articles from different ICT conferences.
