在使用while循環時驗證用戶的輸入

Question

我的問題是我試圖驗證我的輸入，確保while循環僅佔用超過10的數字。否則，他們必須重試。但我遇到的問題是，如果我關閉while循環，循環不斷重複。

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); 
     } 
    } 
}

while(floor >=10){ // Do whatever you want } 通過這個基本while loop tutorial。
