Question

I have finished learning java recently.I want to know which course is better to start after learning java.
actualy, I want to know which programming language is similar to java?
or which one help me in java?

Answer 1

I second what Full Gamer said. Kotlin is interoperable with Java (can mix the code and it'll still execute) and greatly improves upon Java, so it's worth learning and is a language you'll continue to hear more & more about in the future.

Answer 2

@Amir

Exact same usage as Java. It's a language that was created off of the JVM (so it can run on ALL devices that Java can) and meant to better the language & resolve issues that exist in Java. They've done an excellent job on it, and even Google recognizes the language as an official Android development language. However, it's far from being bound to mobile devices, so use it anywhere you see Java used.
