A static nested class in Java serves a great advantage to namespace resolution. This is the basic idea behind introducing static nested classes in Java. For example, if you have a class with an exceedingly common name, and in a large project, it is quite possible that some other programmer...
Since theinner classexists within the outer class, you must instantiate the outer class first, in order to instantiate the inner class. Here's an example of how you can declare inner classes in Java. Example 1: Inner class classCPU{doubleprice;// nested classclassProcessor{// members of ne...

You can even implement the surrounding interface in the inner class. It's convenient to nest a class inside an interface when you want to create some common code to be used with all different implementations of that interface. Java TestBed$Tester ...
