In this application we are going to deal with composition. Create a class named Professor and another named Course. Besides these classes we will have a class named Main for placing the main method. Professor class should contain variables id (string) and name (string) alongside their respective setters/getters. Course class should contain variables id (string), name (string) and professor (Professor) alongside setters/getters. Course also contains a toString method, which prints the course id, course name and professor information. In main, create a professor first. Ex: A123 Alihan Hadimlioglu Then create a course. Ex: CE343 Object-Oriented Programming Languages (These will be taken from the user and you must handle exceptions). Then assign the professor you previously created as the course professor variable. Finally, display the course information
