package qiu;            import  java.util.*;public class si {   Scanner input=new Scanner(System.in);      String name;   double price;   public void a(){   int cai=(int)(Math.random()*10);   switch(cai){   case 0:   case 1:   case 2:   case 3:   name="自行车";     price=666;     break;   case 4:   case 5:   case 6:   name="员康杰";   price=66;   break;   case 7:   case 8:   case 9:   name="老冰棍";   price=0.5;   break;        }   } public void b(){   System.out.println("猜测"+name+"价格:");   double ce=input.nextDouble();   boolean aaa=false;   for(int q=0;q<=3;q++){   if(price>ce){   System.out.println("再大点!");    }else if(price<ce){   System.out.println("再小点");     }else {   System.out.println("恭喜 你猜对了");   aaa=true;   break;   }System.out.println("再猜一次吧");   ce=input.nextDouble();   }if(!aaa){   System.out.println("智障再见 ");   }   }                              }
