Create a Part 3 subpackage p3 under the hw1 package and copy here the Course, Grizzly, Student and Hw1Test classes from subpackage p2. In the p3 subpackage, create a public class named Instructor as a subclass of the Grizzly class, and add the following private data field to the Instructor class: - courses, which is an Array List of Course objects each representing a course the instructor teaches. Create the following methods in the Instructor class in the p3 subpackage: - A constructor public Instructor (String name) that uses the constructor of the Grizzly superclass to create a Grizzly object with the given name, and initializes the courses field to an empty list. - A tostring() method that returns a string of the format Instructor {1d: _ nane: __ courses: where the underscores after "id: " and "name: " should be replaced with the values of the respective fields, and that after "courses: " should be replaced with a list consisting only of the names of the courses the instructor is teaching. In the Course class in the p3 subpackage: - Add a private data field named instructor which is an object of the Instructor class that represents the instructor of the course. - Add getter and setter for the instructor field. - Change the tostring method so that it returns a string of the format Course\{nane: _, instructor: _ _ capacity: _ roster: _ } _ 7 where the underscore after "instructor: should be replaced with the name of the instructor field if it is not null. Otherwise (i.e., if the instructor has not been assigned), then use "TBO" for the name. In the Instructor class, add a method public void teachCourse (Course course) that assigns this Instructor object to the instructor field of the Course object in the argument, and adds the given course to the courses field of this Instructor object. Run the main method of the Hw1Test class in the p3 subpackage. You should see Add the following code to the end of the main method of the Hw1Test class in the p3 subpackage: - Create two Instructor objects whose names are Evelyn and Richard, respectively. Print the two Instructor objects. - Have Evelyn teach ITEC 4320 and ITEC 4700 , and have Richard teach ITEC 4860 . - Print the two Instructor objects. Your code should print Instructorfid: 5, name: Evelym, courses: [ITEC 4320, ITEC 4700]) Instructorfid: 6, name: Richard, courses: [ITEC 4360]) - Print the three Course objects. Your code should print Courseiname: ITEC 4320, instructor: Evelyn, capacity: 3, roster: [Carol, Daniel, Bob]] Course-name: ITEC 4700, instructor: Evelyn, capacity: 3, roster: [Alice, Bob, Daniel]? Course-name: ITEC 4260, instructar: Richard, capacity: 3, roster: [Carol, Daniel, Alice]\}
