Grade Calculation

Class Teacher of class V, was busy in calculating the grade for each student in her class, based on his/her total marks obtained in SA1 assessment. Help the class teacher in completing the task quickly by providing a Java Solution . Implement the solution using Threads so that the task can be completed faster.

Consider the class given below.

<> - Thread

Thread()

run()

<> - GradeCalculator

private studName String

private marks int

private result char

getstudName() String

setStudName() String

getMarks(): int[]

setMarks()

getResult():char

setResult():char

GradeCalculator(String,int[])

run():void

<> - Main

Main()

Creat a class called GradeCalculator that extends Thread with the following private attributes.

String studName,

char result,

int[] marks

Include appropriate getters/setters.

Writ a two argument constructor in the GradeCalculator class with arguments - name and marks. And set the values via constructor.

Writ a main class and implement the below task

Get the number of threads initially from the user. Each Thread is responsible for calculating the grade of respective student.

Hint: Override the run method to implement the above task

Assumption: Each student will have only five subjects and marks of each subject will be greater than or equal to 0 and lesser than or equal to 100. Hence the maximum Total marks obtained by each student will be 500. And the minimum Total marks obtained by each student will be 0.

Calculate the grade based on total marks (sum of all marks) obtained by each student as below and set the same in result attribute of GradeCalculator class for respective student

Total Marks Grade

400 to 500 A

300 to 399 B

200 to 299 C

Less than 200 E

Display the result as shown below

Sample input/output
