1. Write Java classes for the following class diagram. You don't need to write any set and get methods for simplicity.

 

II. Write a Java class for the following class diagram. You don't need to write any set and get methods for simplicity.

Class StudentScore

+ stuName : string

+ gpa : double

+ totalScores : HashMap<String, double>

+ program : string

+ StudentScore(// declares necessary parameters)

III. Write the following method that takes an LinkedList of Student objects as argument and . create a HashMap of StudentScore objects. Each object's totalScores is a HashMap of courses' total homework scores for each Student object in the LinkedList

HashMap<String, StudentScore > getScoreList( LinkedList <Student> list)

IV. Write the following method to print all the student objects in the LinkedList. void printAll( HashMap<String, StudentScore > scoreList )

V. Write the following method that takes an ArrayList of StudentScore objects and write all items to a Text file. Each field is separated by a tab \t. In your method, you need to use "try with resource" statement. Here is a sample of the file.

void saveFile( ArrayList<StudentScore > scoreList )

Name   Peter	GPA   3.8	Program   MSEE	TotalCourses   2
EE205	80
EE450	70
Jim	3.5	MSCS	3
CS204	70
CS350	10
CS360	100

VI. Write a method that returns the ArrayList<Student> of Student objects who has only one homework score in any of his/her courses.

public ArrayList<Student> getProblemStudents(LinkedList<Student> list)
