Java 14 was released recently on March 17. It has features that are more useful for mobile app development than older versions, like Java 13 and Java 12. Java is one of the most popular languages with 18.84% share after Python.
Ease of multi-threading, API integration, and in-built security features make Java one of the most sought after programming language for app developers. Most important is its ease of integration of compatibility features that are updated regularly by operating systems. Android 11 releasing this year will have several new compatibility features, which can be easily integrated with Java.
