Make sure you are really typing:

java --version

If so, try with a single dash like:

java -version

  1. Remove /usr/lib/jvm , this will remove jdk from your system
  2. Now again install using sudo apt install default-jdk
  3. Check command java-version, and it shows current installed version.

This worked for me!
