Extracted text: Consider the following UML diagram. Suppose that each of these classes has a getMass () method that returns the mass of the current object (double); that the Star class has a getPlanets () method that returns an array of Planet objects (the planets that orbit this planet); and that the Planet class has a getMoons () method that returns an array of Moon objects (the moons if this planet). All attributes of these classes are private. All methods described above are public. Star 0.. Planet Create a class called SolarMass that has a single class method in it called solarMass (Star theStar) that returns the total mass of the input star (along with the mass of all of that star's planets and their moons). The method returns a double. Any program should be able to call this method. e..* Moon
