When a Java class is compiled, a class file with the same name is created. However, in the case of nested classes or nested interfaces, it creates a class file with a name combining the inner and outer class names, including a dollar sign. In this article, we’ll see all those scenar...

When you’re creating a standalone program such as this one, one of the classes in the file must have the same name as the file.That class must contain a method called main( ). The args won’t be used in this program, but the Java compiler insists that they be there because they ...
