在使用while循环时验证用户的输入

Question

我的问题是我试图验证我的输入，确保while循环仅占用超过10的数字。否则，他们必须重试。但我遇到的问题是，如果我关闭while循环，循环不断重复。

import java.util.Scanner; 
/** 
* @(#)Hotel_Occupancy.java 
* 
* Hotel_Occupancy application 
* 
* @author 
* @version 1.00 2013/10/28 
*/ 

public class Hotel_Occupancy { 

    public static void main(String[] args) { 

     //Declare Variables 
     int floors; 
     int rooms; 
     int roomsOccupied; 
     int roomsVacant; 
     int occupancyRate; 

     //Create Scanner Object 
     Scanner keyboard = new Scanner(System.in); 

     //Ask user for # of floors 
     System.out.print("Enter floors? Input number more than 1. "); 
      floors = keyboard.nextInt(); 

     while (floors < 1 && floors != 10) 
     { 
      System.out.println("ENTER VALID NUMBER."); 
      System.out.println("Enter floors? Input number more than 1. "); 
      System.; 

      //Create loop with floor iteration 
      for (rooms = 1; rooms <= floors; rooms++) 
      { 
       System.out.println("How many rooms? "); 
       rooms = keyboard.nextInt(); 
      } 

      for (roomsOccupied = 1; roomsOccupied <= rooms; roomsOccupied++) 
      { 
       System.out.println("How many rooms occupied? "); 
       roomsOccupied = keyboard.nextInt(); 
       roomsVacant = rooms - roomsOccupied; 
       System.out.println("Rooms Vacant" + roomsVacant); 
      } 

      //Calculate Occupancy Rate 
      occupancyRate = roomsOccupied + rooms; 
      System.out.println("Occupancy rate is " + occupancyRate); 
     } 
    } 
}  

Answer 1

while(floor >=10){ // Do whatever you want } 通过这个基本while loop tutorial。
