why a class can't declare it as static ?

[Edward Chen]

why a class can't be declared as static , like "public static class Test" ?

Thanks.

Edward:

External (main file) classes cannot be declared static. Internal classes can. What would it mean for an external class to be static?

An enum with one member has all the properties you would expect from a static class, like

public enum MyClass {
   STATIC;

   public void method() {
      // ...
   }

   // more methods
}
//
MyClass.STATIC.method(); // usage

In fact this is by many considered the preferred implementation of a so called Singleton.
