Based on the code below use a word processor to create a class diagram for it.

Code:

import java.util.Scanner;

public class PlanetTesterV3 {

public static void main(String[] args) {

// declare variable

int grade1 = 85;

int grade2 = 92;

// create student object and pass the grade the value

StudentV3 obj1 = new StudentV3(grade1, grade2);

// calculate the average and difference

double average = obj1.calculateAverage();

int difference = obj1.calculateDifference();

// display the value

System.out.println("\t\t\tGrades:");

System.out.println("Grade1\t\tGrade2\t\tAverage\t\tDifference");

System.out.println("==========================================================");

System.out.print(grade1 + "\t\t" + grade2 + "\t\t" + average + "\t\t" + difference);

}

}

//create a class

class StudentV3 {

// declare private variable

private double grade1;

private double grade2;

// set the constructor

public StudentV3(double g1, double g2) {

this.grade1 = g1;

this.grade2 = g2;

}

// calculate the average of grade

public double calculateAverage() {

return (grade1 + grade2) / 2;

}

// calculate the grade difference

public int calculateDifference() {

if (grade1 > grade2)

return (int) (grade1 - grade2);

else

return (int) (grade2 - grade1);

}

}

sample output:

Grades:

Grade1 Grade2 Average Difference
