class - Why do C++ classes not have access specifiers like classes in Java have? -


i'm new c++, , i'm familiar java. first thing wondering when started looking @ c++ code classes (not members) don't have access specifiers such private, protected , public. exemples here , here. 

public class { // line.   private class b { } // not line. }

why so?

there's no access modifier @ level of classes, since language has no concept of package. there @ level of data members, member functions , inheritence:

class foo {}; class bar : public foo {   public:   void bar() const {}  private:   int bar_(float) {}   int a, b, c;  };

the closest can declaring nested classes inside class:

class foo {    struct bar0 {     void bar0() const {}   };   struct bar1 {     bar0 b0;     bar1() { b0.bar0();}   };  };
