Question

Create a program that contains 4 methods / functions... main(), getTestScores(), calcAverage(), and displayAverage(). The main() method should call the getTestScores() method to get and return each of 3 test scores. The main function should then call the calcAverage() method and send the three scores down to calculate and return the average of the three test scores. The main() method should then call the displayAverage() method to display the average of test scores.

Answer 1

Answer:

import java.util.Scanner;

public class  num6{

   static int getTestScores(){

       System.out.println("Enter the Score");

       Scanner in = new Scanner(System.in);

       int score = in.nextInt();

       return score;

   }

   static double calcAverage(int score1, int score2, int score3){

       return (score1+score2+score3)/3;

   }

   static void displayAverage(double ave){

       System.out.println("The Average is "+ave);

   }

   public static void main(String[] args) {

       int num1 = getTestScores();

       int num2 = getTestScores();

       int num3 = getTestScores();

       //Calling Calculate Average

       double average = calcAverage(num1,num2,num3);

       //Calling displayAverage

       displayAverage(average);

   }

}

Explanation:

• Using Java programming Language
• Create the four methods
• getTestScores() Uses the Scanner Class to receive an in variable and return it
• calcAverage() accepts three ints as parameter calculates their average and return it
• displayAverage() Accepts a double and prints it out with a concatenated string as message
• In the Main Method, getTestScores is called three times to obtain three numbers from the user
• calAverage is called and handed the three numbers
• printAverage is called to output the calculated average
