Maybe for the backend, but for the frontend Java has messed up really bad. Some of the worst aberrations ever created in the history of software development are Java frontend frameworks: think JSF to start.

There is nothing like Javascript for the frontend, and if its for developing micro-services and not monoliths I think Javascript is also a pretty good choice for the backend as well. There are some good solid libraries like express, sequelize, passport.js that be used to build solid micro-service backends, in every way comparable in functionality and performance to Java.
