i3保证大于0就行了吧,不用&&i3<7,应该允许重复租用车辆的
个人见解
很不错了
System.out.println("请您选择租车数量:");
Scanner input2=new Scanner(System.in);
int i2=input2.nextInt();
放到了
else if(3>0&&i3<7){
}
里面
-------------------------------------------------------------------
sum=sum*sum1
改成
sum=sum*sum1*i2;
--------------------------------------------------------------------
for(int i=1;i<i2+1;i++) { 这行删除
System.out.println("请输入您要租用的第"+i+"辆车的编号");
这个改成
System.out.println("请输入您要租用辆车的编号");
