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 )
