收到下面提到的程序的“线程”main“java.util.NoSuchElementException中的异常”错误 [duplicate]

问：

在这里，它只执行一次，然后给出下面给出的错误。 请帮助解决我遇到的这个问题

package project1;

import java.util.Scanner;

public class factorial {

public static void main(String[] args) {
    String y;
    do {
        Scanner sc = new Scanner(System.in);
            
        int flag = 1;
        System.out.println("Print the number:");
        int n = sc.nextInt();
            
        for (int i = 1; i <= n; i++) {
                flag *= i;
        }
        System.out.println(flag);
        System.out.println("Press Y/y to continue");
        y = sc.nextLine();
            
        sc.close();
      } while(y == "Y" || y == "y");
   }
}

输出：（获取异常 java.util.NoSuchElementException）

Print the number:
12
479001600
Press Y/y to continue

y
Print the number:
Exception in thread "main" java.util.NoSuchElementException
