i have doubts access modifiers used top level classes in java. 1) can access modifier public or default used top level classes or nested classes? 2) lets there 2 different classes , b, both in different packages. in order have access (acess class members) class class b , both top level class, ‘a’ class members should defined public, right ? if either class or class members not public class b not have access class a, right ? please correct if i'm wrong. 1) nested classes can have same access modifiers top level classes. 2) in order access class class b, needs public. class b may package private (default). b can access methods of if a's methods public (if b not inherit a). if class package private, doesn't matter if contains public methods - won't accessible b. see oracle docs , this stackoverflow thread .
