simple as it is: The constructor allways creates a instance of the class it's the constructor of. No need to specify anything.

Would not make sense if you would try to construct a Rectangle and get a String as return.

At least for this last question the answer was kinda obvious if you would have thought bout it.

Maybe a bit nitpicky, but the constructor doesn't create an instance of the class. The constructor execution comes late in the process, as described in the Java Language Specification.

Should have said probably you call the constructor to create a instance :)
