Listing 10.6-Course.java public class Course private String courselane private Stringt) students- new Stringt11001 private int numberofstudents publie Course (String courselane) this.courseName courseNanez public void addstudent (String student) students [numberofstudents]- student numberofstudents++ publie StringI1 getstudents O return studentS publie at getNunberorstudentso return numberofstudentsi publie String getcourselane O return courselase publie void dropstudent (String student) Left as an exereise in Exereise 99 The implementation listed above will crash i more than 100 students are added.
