Prerequisites :- Nested Classes in Java It is an inner class without a name and for which only a single object is created. An anonymous inner class can be useful when making an instance of an object with certain “extras” such as overloading methods of a class or interface, without having to actually subclass a class. In Java, nested classes can be either static or not. If they are static, they do not contain a reference to the pointer of the containing instance (they are also not called inner classes anymore, they are called nested classes).. Forgetting to make an nested class static when it does not need that reference can lead to problems with garbage collection or escape analysis. Java 5 « Previous; Next » Which is true about an anonymous inner class? Options - It can extend exactly one class and implement exactly one interface. - It can extend exactly one class and can implement multiple interfaces. - It can extend exactly one class or implement exactly one interface. - It can implement multiple interfaces regardless of whether it also extends a class. CORRECT ANSWER ... Answer: (d) It has no class name. Explanation: Anonymous inner classes are the same as the local classes except that they don't have any name.

It can extend exactly one class or implement exactly one interface. D. It can implement multiple interfaces regardless of whether it also extends a class. In this tutorial, we'll consider anonymous classes in Java. We'll describe how we can declare and create instances of them. We'll also briefly discuss their properties and limitations. 2.
