第三章习题3-第三题=改写彩票例题

问题：

用if-else if-else 多条件分支语句代替switch语句来判断彩票的中奖情况，允许彩票号码中含有0.

代码：

Test .java

import java.util.Scanner;  
public class Test {  
    public static void main(String[]args){  
        Scanner reader=new Scanner(System.in);  
        System.out.println("Please enter your caipiao number: ");  
        int number=reader.nextInt();  
        Administractor person=new Administractor();  
        person.getmess(number);  
          
          
    }  
}  

public class Administractor {  
    void getmess(int number){  
        if(number>100000||number<10000){  
            System.out.print("please enter your number: ");  
        }  
        else  
        {  
        int one=number%10;  
        int two=number%100;  
        int three=number%1000;  
       if(one==9||one==3||one==1){  
            System.out.println("Good luck! you won the third prize! ");  
       }else if(two==29||two==46||two==21){  
             System.out.println("Good luck! you won the second prize! ");
       }else if(three==875||three==326||three==596){  
           System.out.println("Good luck! you won the first prize! ");      
        }   else{
            System.out.println("Sorry,very pity,it is not the second prize! ");        
        }     
        }     
    }  
      
}  

运行结果：

总结：

要理清循环之间的关系。
