Answer 1

The purpose is specified in the javadoc. It is to specify that cloning of an object of this type is allowed.

If your class relies on the built-in implementation of clone() (provided by the Object.clone() method), then this marker interface enables field-by-field cloning. (If you call the built-in clone method on an object that doesn't implement Cloneable, you get a CloneNotSupportedException.)
