System.out.println("欢迎使用答答租车系统");

System.out.println("您是否要租车：1.租车  2.退出");

Scanner scan=new Scanner(System.in);

String input=scan.next();

if(input.equals("1")){

System.out.println("您可租车的类型及其价目表");

System.out.println("序号\t名称\t租金\t容量");

}

}

}

Answer 1

接下来可以用foreach把carsForRent中的数据打印出来，但是要考虑到车种类的不同显示“载客量”or“载人数”。
