The Java "installers" have always been flaky. Here the thing, you don't "install" Java. Here's all you need to do (assuming it's a Windows system, but other systems aren't much different):

  1. download the binary

  2. decompress the binary wherever you want it.

  3. edit your system environment variables and create a new one called JAVA_HOME. The value should be the full path of the folder you just extracted.

  4. edit the PATH and add %JAVA_HOME%\bin to the list.

  5. restart and command Windows, terminals, or IDEs. Java is ready to go.

In mac and kinux sdkman provides a great way to manage multiple jdk installs.

You may find jwmv useful. You uninstall existing Java and then use jwmv
