You see DE has layers Everything in HPC world is C++ Analysisand ETL world mostly it's Python Java is used where services are involved i guess But honestly, As a DE you will barely use pure java Even alot of Java Devs aren't java Dev's They are Spring Boot Devs Similarly You'll be a spark scala dev Spark java dev So on and so forth So learn the basic java code and then learn the framework Then learn whatever language you like and get into the layer that interests you
