Sorry, but previous answer by Yayati Pavan does not answer the question. If that answer is true then there should not be a problem with a "protected" class, as "protected" keyword is wider than default one.

There are no protected class because it is unnecessary to have them. Access modifiers for classes determine 2 things

i) If a class can create instance of other class ?
ii)If a class can extend other class ?

Now, any class within the same package will be able to create an instance of "protected" class - this is true for default-accessor and public classes. No class outside the package will be able to create an instance of "protected" class - this holds good for default-accessor classes.

Again, for a "protected" class by its definition will be extendible by any class within its package - so is default-accessor class, and extendible for any class outside its package - so are all public classes.

Both of this reason nullifies the reason for a protected class.
