I don't know if you really
had to uninstall
over other versions of Java. There are
ways to manage multiple versions of Java without uninstalling. On my Mac, I run the
java_home utility and I have all versions from JDK 6 to 8 installed. If I need to switch to a different version of Java, it's a quick trip to a Terminal window to run one command (I wrote a shell script to make it even easier).
