Number tudents in course1: 3 10.5 Case Study: Desi ook provides a peter Jones, Kim Smith, Anne Kennedy, Number of students in course2: 2 section and the nd has students n use a class to The Course class is implemented in Listing 10.6. It uses an array to store the studer course. For simplicity, assume the maximum course enrollment is 100. The array using new String [100] in line 3. The addStudent method (line 10) adds a stude array. Whenever a new student is added to the course, numberOf Students is increa as an exercise. 12). The getStudents method returns the array. The dropStudent method (line he course.

You can improve the class by automatically increasing the array size in Prog Exercise 10.9 Whdent ( student: String ) : void Adds a new student to the cour +dropStudent (student: String) : void Drops a student from the course +getStudents ( ) : String[ ] Returns the students for the cou +get NumberOfStudents ( ) : int Returns the number of students FIGURE 10.10 The Course class models the courses. A Course object can be created using the constructor Course (String a course name. You can add students to the course using the addStudent (Str method, drop a student from the course using the dropStudent (String studer return all the students in the course using the getStudents ( ) method.
