BlueJīlueJ provides an integrated educational Java development environment for Java beginners. With all that code written in Java, that means there are some great options for integrated development environments (IDE) to give developers all the tools needed to effectively write, lint, test, and run Java applications.īelow, I introduce-in alphabetical order-my five favorite open source IDE tools to write Java and how to configure their basics. Regardless, Java consistently ranks in the top three of programming languages in use today with a community of seven to ten million developers in the TIOBE Index. Controlling this much scope requires more code, making it difficult to minimize memory footprint or speed up startup times for new applications. These frameworks were designed and developed to run any application on any server environment that includes dynamic behaviors in terms of parsing annotations, scanning descriptors, loading configurations, and launching the actual services on a Java virtual machine (JVM). Java frameworks make life easier for programmers by streamlining their work.
