JetBrains Rider vs. Oracle Java SE

Initially you may think it’s not worth paying and that there are better free options, which is definitely a lie we once tried to live with. It has everything you may ever need in .NET world, code analysis and debugging works super well and all the SQL/noSQL related integrations are just next level compared to the competition. It’s worth every penny.

Oracle Java SE is well suited to long-running applications (e.g. servers). Java Swing (UI toolkit) is now rather outdated, lacking support for modern UI features. JavaFX, the potential replacement for Swing, has now been separated out of Java core. Ideally, there would be a path to migrate a large application incrementally from Swing to JavaFX, but due to different threading models and other aspects, it is difficult. At this point, it is probably better to use an embedded web browser (e.g. JxBrowser) to provide a modern UI in HTML/Javascript and keep just the business logic in Java.

• Provides a smooth, efficient IDE for developing .NET applications. Performance has been much better than Visual Studio in my experience.
• Integrated refactoring tools are really comprehensive and useful.
• Integrates with other JetBrains products such as TeamCity, Upsource, dotTrace, etc.

• Plenty support built into the tool and IDE like Maven, Ant, Eclipse, IntelliJ.
• Strong object-orientation language and clear project structure.
• Wrapper underlines hardware and memory management so the developers can focus on business and implementation.
• It offers a huge library and framework support from third-parties and the community.

• Startup time. It takes a while to index big projects.
• Rarely it loses the intellisense and the only way to get it back is by restarting.
• Memory usage for big projects

• Commercial Licensing in 2019. Oracle will charge commercial organizations using Java SE for upgrading to the latest bug fixes and updates. Organizations will now need to either limit their implementation of Java SE or may need to drop it altogether.
• Slow Performance. Due to the all of the abstraction of the JVM, Java SE programs take much more resources to compile and run compared to Python.
• Poor UI appearance on all of the major GUI libraries (Swing, SWT, etc.). Through Android Studio, it is easy to get a native look/feel for Java apps, but when it comes to desktops, the UI is far from acceptable (does not mimic the native OS's look/feel at all).

Due to the performance and productivity benefits we get with Rider, we will continue to use it for the foreseeable future.

Rider is a great IDE with extensive C# refactoring support and .NET-specific knowledge. This is great for building .NET applications but for our purposes, the Unity specific suggestions are really helpful.

JetBrains Rider is great as an editing and debugging environment. It reliably connects to the Unity editor and allows debugging, which some IDEs are not as reliable at doing.

Oracle Java SE provides the new features along with timely security patches. New features like Record patterns and pattern matching for switches are very useful. With every new release of Java, it is getting better. Sequenced collections are also an interesting feature added to Java. With all these new features, backward compatibility is also maintained.

The support forums and knowledge base are extensive and the JetBrains support staff respond quickly to new posts and help resolve issues. There is also a publicly accessible issue tracking system, which allows you to stay on top of any bug fixes or enhancement requests.

Java is such a mature product at this point that there is little support from the vendor that is needed. Various sources on the internet, and especially StackOverflow, provide a wealth of knowledge and advice. Areas that may benefit from support is when dealing with complex multithreading issues and security libraries.

Rider is hands down smoother and way less glitchy than Visual Studio Enterprise. There are way more refactoring capabilities and spell check so that your code is readable, maintainable, and easy to follow. Since Rider is cross-platform, our developers are no longer constrained to only using Windows. We can now get a familiar development environment across Mac, Windows, or Linux!

Chose to go with Java instead of Python or C++ due to the expertise on the ground with the technology, for its ease of integration with our heterogeneous setup of production servers, and for the third party library support which we've found was able to address some challenging aspects of our business problem.

• Built in Resharper into the license fee, great, you likely want it
• Demands less resources from computer so needing a beefy work computer might not be the case, save money on equipment.

• The different versions make it harder to work with other companies where some use newer versions while some use older versions, costing time to make them compatible.
• Licenses are getting to be costly, forcing us to consider OpenJDK as an alternative.
• New features take time to learn. When someone starts using them, everyone has to take time to learn.
