The Planet class is a non:abstract child of solarobject and defines one functions: int getNumberofMoons 0,as shown in the figure. In addition, the Planet class implements two interfaces. Revolve, and Rotate. The Revolve interface defines a single function: string getrearLength (),as in the figure. The Rotate interface defines a single function: string getDayLength as in the figure. The Planet class has one child, Moon The Moon class is d defines one functions: String get Parent Planet o, as shown in the figure From the description, above, complete the following
