How delete all elements Java 64 bits mac

[Noél Dubau]

Hello

On my recent new MacBook as I was asked to hace a Java environment bay launching a FMP File using SMaster I think I commited an error : I installed le 64 bits version I found on Java jre-8u121-macosx-x64... I get errors in my app which works fine on my iMac ; I tried to reinstall the special version for mac but nothing changed.

My question is how to fully uninstall every java on my MacBook under El Capitan and reinstall a functionnal version ?

Thanks
