Most companies have applications entirely based on microservices or are currently moving to a microservices architecture. Modular-monolithic applications account for 13% of responses, and service-oriented architectures - for 12%. Microservices-based applications are the most popular (32%), followed by monolithic applications (22%). Java Application Architecture Trends: Microservices and Monolithic ApplicationsThe developers also have spoken about the architecture of the applications they have developed. Generic OpenJDK and AdoptOpenJDK/Adoptium are also among the top three with 27% and 16%, respectively.Ģ.3% of developers choose distributions of OpenLogic OpenJDK. Which JRE/JDK distributions do you prefer?36% of respondents prefer Oracle Java. The programming languages Kotlin, Groovy, and Scala were the least popular amongĭevelopers, but collectively 17% of the developers surveyed use them. Next, come Java 12 or newer (12% of developers) and Java 7 or older (5% of respondents). Java 11 occupies the second place (it’s popular among 29% of developers). Which JDK version do developers choose?Most developers say they use Java 8 (37% of those surveyed) as their programming language in their primary application. In this text, we have collected the main results of the survey. Developers from the US, China, and Europe answer the questions about significant industry trends: popular JDK versions, application architecture, and build tools. Last but not least, it must be said that the JVM plugin can handle development in remote and cloud environments as well as in microservices.Every year, JRebel, a company that develops tools to improve the efficiency of Java programming, conducts a survey. If you are curious about whether JRebel’s capabilities extend to modifying static resources files and annotations or file-based configurations, you may rest assured since it can do that for various renowned Java libraries. What’s more, it should be noted that IDE workspaces and build systems are the sources of static resources and classes.Īside from that, JRebel can rebuild caches and is capable of rewiring components and applying configuration changes to the runtime, with more than 100 frameworks being compatible. As a result, any modified classes are recompiled and can be reloaded in real time in the running program. To be more specific as to how the software utility can be of help, it should be mentioned that it can make classes reloadable by relying on existing class loaders on app servers. Aside from that, developers may be interested to know that application server support for Tomcat, Jetty, WebLogic, WebSphere, JBoss EAP/Wildfly, OSGi, and GlassFish is offered. Being designed as a smart way of avoiding carrying out repetitive and tiresome tasks while developing Java applications, JRebel is a JVM plugin that can be of great help to any professional interested in inspecting code changes in real time without affecting the program state in any way.Īs for the sphere of influence a product such as JRebel boasts, it is worth pointing out that it should integrate with any of the following IDEs: IntelliJ, Eclipse, RAD, NetBeans, MyEclipse, and STS.
