Question 1: (15) Create a class Book. Its data members are author (String) chapterNames[100] (String[]) Create two overloaded constructors, one with no argument and one with two arguments. Create a method compareBooks that compares the author of two Books and returns true if both books have same author and false otherwise. (This method must manipulate two Book objects) Create a method compare ChapterNames that compares the chapter names of two Books and returns the book with larger chapters. Display the author of the book with greater chapters in main. Create a runner class that declares two objects of type Book. One object should be declared using no argument constructor and then the parameters should be set through the set() methods. The second object should be declared with argument constructor. Finally the CompareBooks()and compareChapterNames method should be called and the result should be displayed in the runner class. Draw a UML Diagram of given above scenario
