After Learning Java, what other language should i learn?

you can go for php, C#,Ruby and many more… They are somehow related to java. Ruby is very popular nowadays, if you are interested in web development you can try ruby first....by the way I didn't even start that.😛

I think you should go for java frameworks.

If you know Java thoroughly then c++ will be easy to learn. after that you can go for python.

Kotlin, Clojure, rust, Haskell are all very good languages that will teach you to be a highly disciplined programmer.

learn pHp

Try to learn other object oriented programming like, C++, C#, PHP5
