4Anonymous class(匿名类) 没有类名的局部类就是匿名类。用一条语句完成匿名类的定义与实例创建。例 如如下代码: publicclassOuter { publicvoidinstanceMethod() { //define a nonymous class which implements Action interface and creat an instance of it Action action=newAction() { publicvoiddoAction() ...
每个inner class都能够各自继承某一实现类(implementation)。因此,inner class不受限于outer class是否已继承自某一实现类。 如果少了inner class所提供的“继承自多个具象(concrete)或抽象(abstract)类”的能力,设计上和编程上的某些问题会变得十分棘手。 所以,从某个角度来看inner class,你可以说它是多重继承问题的...
Anonymous inner classes can also be used to provide a similar facility as that provided by inner classes. In this approach, the event listener is implemented as an anonymous inner class. The inner class declaration is incorporated into the syntax needed to register the component with the event l...
A local inner class without name is known as anonymous inner class. An anonymous class is defined and instantiated in a single statement. Anonymous inner class always extend a class or implement an interface. Since an anonymous class has no name, it is not possible to define a constructor for...

Anonymous Inner Class Inner Class An inner class can be private and but once you declare an inner class private, it cannot be accessed from an object outside the class. Example: class aditya { int id; aditya(int i) { id = i;

3. Anonymous This type of classes is declared without a name. Such classes are used when one needs to override a method of a class or an interface. In this case, declaration of the class and instantiation needs to be implemented at the same time. ...
