System.out.println("欢迎使用答答租车系统:");
System.out.println("您是否要租车:1是 0否");
Scanner input = new Scanner(System.in);
int t = input.nextInt();
Qiche[] qiche={
new Keche(500,"奥迪A4",4),
new Keche(400,"马自达6",4),
new Khche(450,"皮卡雪6",4,2),
new Keche(800,"金龙",20),
new Huoche(400,"松花江",4),
new Huoche(1000,"依维柯",20)
} ;
}
}
在Qiche[] qiche = {
new Keche 红线 Cannot instantiate the type Keche
new Khche 红线Cannot instantiate the type Keche
}
