Lab Exercise: Implement the following classes: 1. class Course that includes two instance variables: private String Name; // the course name private int ID; // the course ID Your class should have the following: A constructor that initializes the two instance variables id and name Set and get methods for each instance variable. 2. class Department that includes three instance variables: private String deptName; private Course CRS[]; private int noof Courses; Your class should have the following: . a constructor that initializes the department name, set noofCourses and creates the array with size = noorCourses boolean exist(int) that checks whether the course object with id passed as parameter exists in the array or not. void addCourse (int, String) creates and adds the course if the course with id passed as parameter does not exist in the array. void deleteCourse (int) to delete a course if it exists in the array and displays a proper message. void printCourses() that prints the department name and all the courses in the array. void printCourses Recursively) that prints the department name and all the courses in the array recursively. (Hint: write an additional private helper method] Write the expected time and snare complexity as a comment at the void printCourses Recursively) that prints the department name and all the courses in the array recursively. (Hint: write an additional private helper method] Write the expected time and space complexity as a comment at the beginning of each method of your class. 3. Write a test application named Lab Test. In the main method, do the following: Input the department name and maximum number of courses then create a department object. Input the number of courses in the first set. Input the id and name of each course and add it to the department (Hint: Use a loop). Print the courses. Print the courses using the recursive method. Input the id of a course to be deleted. Delete the course. Print the courses. Input the id of a course to check if it exists and print a proper message Input the id and name of an additional set of courses and add them to the department (Hint: Use a loop). Print the courses. . stc KW LTE 9:25 PM kuwebcont.ku.edu.kw 10* 83% Sample Output Please enter the department name: Computer Engineering Department Please enter the maximum number of courses in the department: How many courses do you have?
