Great work @gzm55 !
The Java port list has been updated to reflect the new capability !

@Cyan4973 as notes in #518 , the performance of this porting is not that outstanding as C version, and even slower than the java version XXHASH64. i think other language porting without vectorize instructions will meet the same situation.

Yes, this is likely.
Accessing vector instructions is important to XXH3 performance.
Each language features its own set of limitations when it comes to vector instructions.
Of course, this is also a moving picture, and improvements also happen.
I can only hope that vector instruction support will improve on Java in the future.
