It became necessary to switch versions when using the latest java and scala for jdk 1.8.0 series projects and individuals.
I used to use jEnv a long time ago, but since the settings were complicated, I reviewed it and found a version control tool called sdkman, which was very easy to use. ..
** How to install sdkman **
curl -s "https://get.sdkman.io" | bash
source "$HOME/.sdkman/bin/sdkman-init.sh"
➜ ~ sdk list java
