The following command switches the current Java platform to Java 8:

$ export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)

$ export JAVA_HOME=$(/usr/libexec/java_home -v 9)

With this command, you are passing the Java version of choice to the -v parameter. But, note that the format is different between Java 8 and 9. With Java 8, the version string is 1.8. With Java 9, the version string is just 9. Traditionally, Java has been using the 1.X version format, for example, Java version 7 had the version string 1.7. This is being changed from Java 9 onward.
