Question

Write a method named printGPA that takes in as a parameter a Scanner to read in user input, and calculates a student's grade point average. The user will type in input containing the student's name, then a number of scores, followed by that many integer scores. Then, the method will print out the average of all grades entered. Here are two example dialogues: Enter a student name: Maria Enter the number of courses: 5 Course 1 Grade: 72 Course 2 Grade: 91 Course 3 Grade: 84 Course 4 Grade: 89 Course 5 Grade: 78 Maria's grade is 82.8 Enter a student name: Jordan Enter the number of courses: 4 Course 1 Grade: 86 Course 2 Grade: 71 Course 3 Grade: 62 Course 4 Grade: 90 Jordan's grade is 77.25

Answer 1

import java.util.Scanner;

public class JavaApplication40 {

   public static  void printGPA(Scanner scan){

       System.out.println("Enter a student name:");

       String name = scan.nextLine();

       System.out.println("Enter the number of courses:");

       int courses = scan.nextInt();

       double total = 0;

       for (int i = 1; i <= courses; i++){

           System.out.println("Course "+i+" Grade:");

           double grade = scan.nextDouble();

           total += grade;

       }

       System.out.println(name+"'s grade is "+(total/courses));

   }

   public static void main(String[] args) {

       Scanner scan = new Scanner(System.in);

       printGPA(scan);

   }

   

}

I hope this helps!
