Question 108 Explanation:
→ Methods declared public in a superclass must also be public in all subclasses (this, by the way, is the reason most of the applet methods are public).
→ Methods declared protected in a superclass must either be protected or public in subclasses; they cannot be private.
→ Methods declared private are not inherited and therefore this rule doesn’t apply.
→ Methods declared without protection at all (the implicit package protection) can be declared more private in subclasses.
→ Methods declared protected in a superclass must either be protected or public in subclasses; they cannot be private.
→ Methods declared private are not inherited and therefore this rule doesn’t apply.
→ Methods declared without protection at all (the implicit package protection) can be declared more private in subclasses.
