java - 我不知道在哪里放置循环

Question

我尝试了 do 循环和 while 循环。我似乎无法弄清楚在哪里放置循环，因此一旦程序完全运行，我希望它询问用户“是的，我想继续”或“否”，然后结束。这是一个类作业，我正在使用 eclipse，它纠正了一些让我自己陷入困境的东西。

代码

import java.util.Scanner;

public class studentgpa {
    public static void main(String[] args) {
        Scanner consoleInput = extracted();
        printGPA(consoleInput);     
    }
    public static void printGPA(Scanner input) {
        System.out.println("Enter a student record: ");
        String name = extracted().next();
        System.out.print("Enter Number of grades you will be entering: ");
        int count = extracted().nextInt();
        int sum = 0;
        System.out.println("Enter Grades: 95 enter 98 enter and so on ");
        for (int i = 1; i <= count; i++) {
            sum += extracted().nextInt();
        }
        double average = (double) sum / count;

        System.out.println(name + "'s grade is " + average);
    }
    private static Scanner extracted() {
        return new Scanner(System.in);
    }
}

您需要将 main 中的内容包装在像这样的 do while 循环中，并提示用户询问是否要继续

do {
    Scanner consoleInput = extracted();
    printGPA(consoleInput);
    System.out.println("Do you want to add another student? (Yes/No)");
    String continue = consoleInput.nextLine(); // storing the user's response
} while (continue.equals("Yes"));
