what is the content meaning when I do a java version - mixed mode

Question

So upon giving command

$java -version 

I get below output.

java version "11.0.10" 2021-01-19 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.10+8-LTS-162)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.10+8-LTS-162, mixed mode)

What does it mean/signify by saying "mixed mode"
