How to downgrade JRE/JDK on Mac OSX?

Question

Does anyone know how to downgrade the version for JRE/JDK from 1.6.0_24 to 1.6.0_18 on a Mac OSX thru Terminal? I need to downgrade in order to get a Java applet working in

Answer 1

I removed the JavaAppletPlugin: /Library/Internet Plug-Ins/JavaAppletPlugin.plugin

and all 1.8 JDKs: /Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk /Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk

Then I was able to re-install 1.7.
