4. Why Clone method is Protected    coderanch.com

here's something to note: if you take a look at the source for Cloneable (note the misspelling---it should really be Clonable) you see this: public interface Cloneable { } yes, it's empty. when you declare a class and put "implements Cloneable" after the class name, there's nothing to implement---well, 'cept the semantics of what the interface represents.

9. Why clone() method in Object class as a "protected" ?    forums.oracle.com

Who cares? To know that you'd have to ask the original designers what they were thinking. Anything else is just speculation. Just use it as is & be done with it.
