Simply put, Java allows us to define classes inside other classes.Nested classes enable us to logically group classes that are only used in one place, write more readable and maintainable code and increase encapsulation. Before we get started, let’s have a look at the several types of neste...
Serializationof inner classes, includinglocalandanonymousclasses, is strongly discouraged. When the Java compiler compiles certain constructs, such as inner classes, it createssynthetic constructs; these are classes, methods, fields, and other constructs that do not have a corresponding construct in the...
Nested types (member types) So far, we’ve seen class types with two different kinds of members: data members and member functions. Our Fruit class in the example above has both of these. Class types support another kind of member: nested types (also called member types). To create a ne...
