Problem with uninstalling java
To uninstall java I followed this.
When I have uninstalled java completely , java -version shows openjdk version "11.0.1" . It's supposed to be no java at all, isn't it?.
Then I've installed java 8, still java -version command yields openjdk version "11.0.1".
I need java for running a bioinformatics tool called Integrative Genomics Viewer(igv). After installing java 8 it continues to tell me I need java 8.
Please help.

1) which Java version(s) have you installed? 2) In Ubuntu/Debian you can install several versions/variants of the same package and then use theupdate-alternativesto make one the default.

Sounds like you did not delete openjdk if it's still listed.
Try running sudo apt-get purge --auto-remove openjdk* to remove the unsupported version of java, then install java 8.
