Member functions of a nested class follow regular access rules and have no special access privileges to members of their enclosing classes. Member functions of the enclosing class have no special access to members of a nested class. The following example demonstrates this: class A { int x; clas...
Static Nested Classes 以及 inner classes 有一些限制规则,下面介绍一下这些规则。 Static Nested Classes访问规则 用Static修饰的Nested Classes,只能访问外部类的非static变量。对于public 的 static Nested Classes 可以用 new 外部类.内部类()的方式直接创建。而默认的static Nested Classes 可以在同一包名下,用 new...

Access privilege in nested classes Member functions in nested classes Friend functions in nested classes See also A class can be declared within the scope of another class. Such a class is called a "nested class." Nested classes are considered to be within the scope of the enclosing class and...

I don't know what you believe you are are achieving with an inner class, but it won't work. Don't use inner classes in C++ unless you really know what it does (for inner classes, protected and private members of the outer classes are seen as if they were public). ...

Nested Classes In addition to defining methods and fields within a class, it is possible to define a class within a class. Such classes are called nested classes. You use a nested class when the class makes little sense outside the context of its containing class. Consider a class that han...
Java nested classes behave the same way, but Java also has the concept of inner classes. To construct an instance of an inner class in Java, you writenew o.InnerClass(...)where...as before are the parameters to an applicable class constructor. Theoin front is an expression that evaluates...
Private constructors are often used in classes that contain only static members. If a class has one or more private constructors and no public constructors, other classes (except nested classes) can't create instances of the class. For example:...
