感觉很难 ,虽然看了老师的分析 但是还是不知道怎么入手
System.out.println("请输入你要租借的天数");
int day=input.nextInt();
System.out.println("你的账单为:");
System.out.println("******可载人的车有:");
for(int b=0;b<x;b++){
if(carNum[b]==5||carNum[b]==6){
continue;
}
System.out.print(carNames[carNum[b]-1]+",");
}
在不在?
if(carNum[b]==5||carNum[b]==6)
这句判断的是什么啊?5?6?

终于写出来了。
不是那么难吧。兄弟
