就是JAVA第二季最后一个综合练习，就是想问如果运用抽象和接口时是不是这样处理和拆分。
package com.imocc;
public abstract class CarSystem {
private int number;
private String name;
private int money;
public int getNumber() {
return number;
}
public void setNumber(int number) {
this.number = number;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getMoney() {
return money;
}
public void setMoney(int money) {
this.money = money;
}
}
package com.imocc;
public interface Passenger {
public void setPassenger(int passengere);
public int getPassenger();
}
package com.imocc;

public void setGoods(int goods);
public int getGoods();
}

public void setPassenger(int passenger) {
this.passenger = passenger;
}
public Bus(int number,String name,int money,int passenger){
this.setNumber(number);
