How do I remove Java 1.7 and replace this with Java 1.6.0_65?

I need to get back to an older JRE specifically Java 1.6.0_65. Right now I have Java 1.7.-_71-b14.

I've tried the instruction in the terminal - sudo rm -fr /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin

That doesn't work. In Terminal mode, a "java -version" query returns the same "Java 1.7..." indicating it has not been removed. What else do I have to do here ?

Thanks
