Sololearn java outdated ? Should i still focus on learning java ?

because in Java 10 we didn't need type data type ...Java 10 supports var keyword

And where do you use java 10? There is a lot of code that is not even on Java 8. Trust me, it's fun to know Java 10 but if you are beginner you should learn something you can use at work. And it's Java 8 in most cases.

ohh .. thanks for clearing my doubts ...

Why do you think that?
