While 循环一直持续到触发特定用户输入

问：

该程序将一个 String 后跟一个整数作为输入，然后使用输入输出一个句子。程序重复，直到键入字符串“quit”。问题似乎出在 nextLine（） 和 nextInt（） 上，但我无法理解它。我收到以下错误：

Exception in thread "main" java.util.InputMismatchException
    at java.base/java.util.Scanner.throwFor(Scanner.java:939)
    at java.base/java.util.Scanner.next(Scanner.java:1594)
    at java.base/java.util.Scanner.nextInt(Scanner.java:2258)
    at java.base/java.util.Scanner.nextInt(Scanner.java:2212)
    at LabProgram.main(LabProgram.java:8)


import java.util.Scanner;

public class LabProgram {
   public static void main(String[] args) {
      Scanner in = new Scanner(System.in);
      
      String inputStr = in.nextLine();
      int inputInt = in.nextInt();
      
      while(!inputStr.equals("quit")){
       System.out.println("Eating " + inputInt + " " + inputStr + " a day keeps you happy and healthy.");
      }  
   }
}

感谢您的帮助，以下代码成功输出：

String inputStr = "";
int inputInt;

while(!inputStr.equals("quit")){
    inputStr = in.next();
    inputInt = in.nextInt();
    in.nextLine();   //this line throws an exception but
                     //program still outputs correctly

    System.out.println("Eating " + inputInt + " " + inputStr + " a day keeps you happy and healthy.");
} 
   }
}
