Switch String,Object -> String,String
remove default constructors

The default constructor will automatically call `super()`.

From http://docs.oracle.com/javase/tutorial/java/IandI/super.html

```
Note: If a constructor does not explicitly invoke a superclass
constructor, the Java compiler automatically inserts a call to
the no-argument constructor of the superclass.  If the super
class does not have a no-argument constructor, you will get a
compile-time error.  Object does have such a constructor, so if
Object is the only superclass, there is no problem.
