Bruce Eckel, Thinking in Java: In Java SE5, Class is preferred over plain Class, even though they are equivalent and the plain Class, as you saw, doesn’t produce a compiler warning. A class must have a matching filename (Car and Car.java). The primitive Java types (boolean, byte, char, short, int, long, float, and double), and the keyword void are also represented as Class objects. Instances of the class Class represent classes and interfaces in a running Java application. For example: the class name is public class Employee{} then the source file should be as Employee.java. Every array also belongs to a class that is reflected as a Class object that is shared by all arrays with the same element type and number of dimensions.
