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;
}

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){

return this.getBrand().equals(c.getBrand())&&this.getType().equals(c.getType());
}

}
//重写父类费用方法
@Override

}else if (days>30){

}else {

}
}
//无参构造
public Cars() {
}
//有参构造
public Cars(String num, String brand, double rent, String type) {

}
//2个有参构造的方法

}
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

}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);

//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;
