Question

1. Write a program using BlueJ and Java to compute the average of three numbers, we will assume these numbers are test scores, so the range the numbers can be are 0-100.

2. The three numbers you will use are: 80, 90, and 95.

3. The average is calculated by adding the three numbers and dividing the sum by three.

4. Your output should look similar to this: Your test score average is: 88

Answer 1

//You should save the below code as Average.java
import java.util.Scanner;
public class Average {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);

        // Prompt for three numbers
        System.out.println("Enter three numbers:");

        // Reading three numbers
        int n1 = scan.nextInt();
        int n2 = scan.nextInt();
        int n3 = scan.nextInt();

        // Calculating sum
        int sum = n1+n2+n3;

        // Calculating average
        int avg = sum/3;

        // Printing average of three numbers
        System.out.println("Your test score average is: "+avg);

    }
