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
+ 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 getScoreList( LinkedList list)
IV. Write the following method to print all the student objects in the LinkedList. void printAll( HashMap 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 scoreList )
