数组根据求和答案输出不正确的元素[关闭]

Question

它通常根据总和的答案正确地输出天数。然而，它似乎只输出“sat”

总的来说，我希望总和的答案是==数组中某一天的一个索引：

java prettyprint-override">while (sum < -10 || sum > 6) {
    System.out.println("Please re-enter First Number: ");
    y = input.nextInt();
    System.out.println("Please re-enter Second Number");
    x = input.nextInt();

import java.util.Scanner;

public class ArrayviaSum {

    public static void main(String[] args) {

        String[] daystring = {"Sat", "Sun", "Mon", "Tue", "Wed", "Thu", "Fri"};
        int y = 0;
        int x = 0;
        int sum = y + x;

        Scanner input = new Scanner(System.in);

        System.out.print("Enter First Number: ");
        y = input.nextInt();
        System.out.print("Enter Second Number: ");
        x = input.nextInt();

        //  **WHILE LOOP WAS HERE FOR VALIDATION**

        if (sum == 0) {
            System.out.println("The day of the given date is : " + daystring[0]);
        }
        else if (sum == 1) {
            System.out.println("The day of the given date is : " + daystring[1]);
        }
        else if (sum == 2) {
            System.out.println("The day of the given date is : " + daystring[2]);
        }
        else if (sum == 3) {
            System.out.println("The day of the given date is : " + daystring[3]);
        }
        else if (sum == 4) {
            System.out.println("The day of the given date is : " + daystring[4]);
        }
        else if (sum == 5) {
            System.out.println("The day of the given date is : " + daystring[5]);
        }
        else if (sum == 6) {
            System.out.println("The day of the given date is : " + daystring[6]);
            input.close();
        }
       
    }

}

在读取x和y的值之前，您将分配给sum。
