Java面向对象实现汽车租赁系统
作者:勤奋的小镇青年、
这篇文章主要为大家详细介绍了Java面向对象实现汽车租赁系统,文中示例代码介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
本文实例为大家分享了Java实现汽车租赁系统的具体代码,供大家参考,具体内容如下
父类Vehicle
public abstract class Vehicle { private String num; private String brand; private double rent; //重写equals方法 public abstract boolean equals(Vehicle v); //计算费用 public abstract double cost(int days,double rent); //3个参数的有参构造 public Vehicle(String num, String brand, double rent) { this.num = num; this.brand = brand; this.rent = rent; } //无参构造 public Vehicle() { } //get,set方法 public String getNum() { return num; } public void setNum(String num) { this.num = num; } public String getBrand() { return brand; } public void setBrand(String brand) { this.brand = brand; } public double getRent() { return rent; } public void setRent(double rent) { this.rent = rent; } }
子类Cars
public class Cars extends Vehicle{ private String type; //重写父类equals方法 @Override public boolean equals(Vehicle v) { if(v instanceof Cars){ Cars c=(Cars) v; return this.getBrand().equals(c.getBrand())&&this.getType().equals(c.getType()); } return false; } //重写父类费用方法 @Override public double cost(int days,double sent) { if (days>150){ return days*sent*0.7; }else if (days>30){ return days*sent*0.8; }else if (days>7){ return days*sent*0.9; }else { return days*sent; } } //无参构造 public Cars() { } //有参构造 public Cars(String num, String brand, double rent, String type) { super(num, brand, rent); this.type = type; } //2个有参构造的方法 public Cars(String brand,String type){ super.setBrand(brand); this.type = type; } public String getType() { return type; } public void setType(String type) { this.type = type; } }
子类Bus
public class Bus extends Vehicle{ private int seat; //重写父类的equals方法 @Override public boolean equals(Vehicle v) { if(v instanceof Bus){ Bus b=(Bus) v; return this.getBrand().equals(b.getBrand())&&this.getSeat()==b.getSeat(); } return false; } //重写父类费用方法 @Override public double cost(int days,double rent) { if (days>=150){ return days*rent*0.6; }else if (days>=30){ return days*rent*0.7; }else if (days>=7){ return days*rent*0.8; }else if (days>=3){ return days*rent*0.9; }else { return days*rent; } } //2个参数的有参构造 public Bus(String brand,int seat){ super.setBrand(brand); this.seat=seat; } //子类有参构造 public Bus(String num, String brand, double rent, int seat) { super(num, brand, rent); this.seat = seat; } //子类无参构造 public Bus(){} //子类get set 方法 public int getSeat() { return seat; } public void setSeat(int seat) { this.seat = seat; } }
汽车业务类VehicleServicer
public class VehicleServicer { public static List initVehicle(){ Vehicle v1=new Bus("京6566754","金杯",800,16); Vehicle v2=new Bus("京9696996","金杯",1500,34); Vehicle v3=new Bus("京8696997","金龙",800,16); Vehicle v4=new Bus("京8696998","金龙",1500,34); Vehicle c1 =new Cars("京NT37465","别克",300,"林荫大道"); Vehicle c2 =new Cars("京9696996","别克",600,"GLB"); Vehicle c3 =new Cars("京8696997","宝马",800,"X6"); Vehicle c4 =new Cars("京8696998","宝马",600,"550i"); //先装入数组中 Vehicle[] ve = {v1,v2,v3,v4,c1,c2,c3,c4}; //将数组转换成集合 List<Vehicle> vehicles = Arrays.asList(ve); return vehicles; } }
测试类Test
public class Test { public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.println("**********欢迎光临秋明山守望者汽车租赁公司**********"); System.out.println("1.轿车 2.客车"); System.out.print("请选择你要租赁的汽车类型:"); int type = sc.nextInt(); //桥车 Vehicle ve; String brand; if(type==1){ System.out.print("请选择你要租赁的汽车品牌(1.别克 2.宝马):"); int pinpai = sc.nextInt(); String model=pinpai==1?"别克":"宝马"; if(pinpai==1){ System.out.print("请输入你要租赁的汽车类型(1.X6 2.550i):"); int leixin = sc.nextInt(); brand=leixin==1?"林荫大道":"GL8"; }else { System.out.print("请输入你要租赁的汽车类型(1.X6 2.550i):"); int leixin = sc.nextInt(); brand=leixin==1?"X6":"550i"; } ve = new Cars(model, brand); }else {//客车 int seat; System.out.print("请选择你要租赁的汽车品牌(1.金龙 2.金杯):"); int pinpai = sc.nextInt(); String s=pinpai==1?"金龙":"金杯"; System.out.print("请选择你要租赁的汽车座位数(1.16座 2.34座):"); int z = sc.nextInt(); seat =z==1?16:34; ve = new Bus(s, seat); } //根据选好的车型,输出车牌和总价 List<Vehicle> list = VehicleServicer.initVehicle(); for (Vehicle v:list) { if(ve.equals(v)){ System.out.print("请输入你要租赁的天数:"); int days = sc.nextInt(); System.out.println("分配给您的汽车牌号是:"+v.getNum()); System.out.println("您需要支付的租赁费用是:"+v.cost(days,v.getRent())); } } } }
