A return type cannot exist in the constructor. It ought to produce and deliver fresh objects. Consequently, a compilation error would result.
Including a return type in a constructor declaration is not allowed. A constructor has to accept one or more input parameters. In the absence of explicitly declared constructors for the class, Java will give a default constructor.
