In this example, the Course class is an aggregat class; it has instructor(a String) and a textbook (a Book) objects as fields. The UML Diagram for the Course class is below: + instructor: String + textbook: Book + Course): Book is a class that has author (a String) and title (a String) as fields. The UML Diagram for the Book class is below: -author: String title: String + Book( au:String, ti:String): Write the complete definition of the no-arqument constructor in the Course class to initialize the instructor to "Alan Turing" and the textbook to "Real Java" by "Ann Smith (NOTE: Do not worry about writing the definiton of the Book class. It has already been defined for you. You can create an instance of the Book class using the constructor specified in the UML Diagram. 1 of 1: Fri Feb 09 2018 21:25:13 GMT-0500 (EST) SUBMIT RESET 2 class Course publie Book textbook 611Inaert Your Code Below -End of Your Code 11 //end class
