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 .

this question has answer here: what correct order of calling superclass methods in onpause, onstop , ondestroy methods? , why? 7 answers i new in java development! may tell me... according logic super.ondestroy(); in destructors goes on top? example: protected void ondestroy() { super.ondestroy(); releasemediaplayer(); } and not protected void ondestroy() { releasemediaplayer(); super.ondestroy(); } like c++, obj-c, pascal, etc ?? it depends on want in ondestroy . super.ondestroy (in order): dismiss dialogs activity managing. close cursors activity managing. close open search dialog if logic put inside ondestroy has 3 things android does, may have worry order. otherwise, , in of cases, not matter.
