Why is Java clone broken?
clone() are “broken” in the sense that they have design flaws and are difficult to use correctly. However, clone() is still the best way to copy arrays, and cloning has some limited usefulness to make copies of instances of classes that are carefully implemented.
Why cloning method is private?
The method is protected because you shouldn’t call it on object, you can (and should) override it as public. In class Object, the clone() method is declared protected. If all you do is implement Cloneable, only subclasses and members of the same package will be able to invoke clone() on the object.

What’s the difference between shallow cloning and sobject?
Consequently, if you make changes to a field on the cloned SObject, the original SObject is not affected. Whereas for Shallow cloning, if you make changes to a relationship field on the cloned SObject, the corresponding field on the original SObject is also affected, and vice versa
