Question

Write a method named printGPA that calculates a student's grade point average. The user will type a line of input containing the student's name, then a number of scores, followed by that many integer scores. Here are two example dialogues:

Enter a student record: Maria 5 72 91 84 89 78
Maria's grade is 82.8
Enter a student record: Jordan 4 86 71 62 90
Jordan's grade is 77.25
For example, Maria's grade is 82.8 because her average of (72 + 91 + 84 + 89 + 78) / 5 equals 82.8. Use a Scanner for user input.

Explanation / Answer

import java.util.Scanner;

public class PrintGPA {

    public static void printGPA() {
        System.out.print("Enter a student record: ");
        Scanner in = new Scanner(System.in);
        String name = in.next();
        int n = in.nextInt();
        double sum = 0;
        for (int i = 0; i<n; i++) {
            sum += in.nextInt();
        }
        System.out.println(name+"'s grade is "+(sum/n));
    }
   
    public static void main(String[] args) {
        printGPA();

    }

}
