Question 1 (20 points] Implement the class Student only. The code of the classes GradStudent and UndergradStudent is provided below. Student - id: int - name: String - courses: ArrayList + Student(id: int, name: String) + getId(): int + getName(): String + setId(id: int): void + setName(name: String): void + getCourses():ArrayList + addCourse(cName: String): void + dropCourse(cName: String): void + toString(): String GradStudent UndergradStudent nbOfCredits Earned: int + UndergradStudent(id:int, name: String, nbOfCredits Earned: int) + getNbOfCredits Earned(): int + setNbOfCreditsEarned(n: int): void + toString(): String - foundInternship: boolean + GradStudent(id:int, name: String, found Internship: boolean) + getFoundInternship(): boolean + setFoundInternship(f:boolean): void + toString(): String A. The Student class is characterized by three data fields: an int id, a String name, and an array list of String courses. Write the following methods: a) A constructor to initialize the id and the name data fields. b) Getters and setters (as shown in the UML). c) addCourse method that takes as parameter the name of the course to be added to the array list. d) dropCourse method that takes as parameter the name of the course to be deleted from the array list. e) A toString method to return information about all data fields. For Example: Student id: 9000123, name: Khaled Haddad, Courses Enrolled: CSCI250, CSCI250L, CSC200, NUTR 100
