This is based on problem 8.7 from the book.

Implement a class Student:

(1) instance variables: name: String scores: a set of grades between 0 and 100 stored in an array or arraylist. If you use array, set its length to be 50;

(2) instance methods default constructor: public Student() which initialize name to be "no name", and create an empty arraylist/array constructor to set the name: public Student(String initName), initialize name to be initName, and create an empty arraylist/array public void setName(String newName): which changes the name to be the new name public String getName(): which returns the name public void addQuiz(int score): add a score public int getTotalScore() public double getAverageScore(): if no score added yet, return 0 else return the average public char getLettterGrade(): if no score, return ' ', else calls getAverageScore, and convert the average score to letter grade, A for 90 and above, ...etc public String toString(): which returns all student name, scores, and letter grade as a single string

(3) use the attached class to test your class, the expected output should be follows:

Name: no name

Scores: [80, 70]

Grade: C

Name: Tom

Scores: [80, 70]

Grade: C

Name: Sally

Scores: []

Grade:

Name: Sally

Scores: [90, 89, 93]

Grade: A
