java - 有没有办法缩短这些命令，以便我不必重复给出 list.add (对于每个所有者)？

Question

正如您在代码中看到的，vehicle() 类是一个父类(super class)。我想保留 2 个单独的类(至少这是我认为最有效的方法。请指出我是否在这里采用相反的方式!)，一个用于车辆，一个用于车辆所有者，其中还列出了所有者的车辆在车辆()类中。基本上，我将使用唯一的所有者 ID 将控制台输入输入到搜索所有者，并显示有关其车辆类型的各种信息字段(如英里数、最高速度、基于购买日期的转售值(value)等)。我想使用高效的编码实践，并将每个对象项添加到列表中对我来说看起来有点尴尬。还有其他出路吗？

下面是我的vehicleOwner类

public class VehicleOwner extends Vehicle{

    private int yearsOwned;
    private String ownerName;
    private int ownerId;

    public VehicleOwner(String ownerBrand, String ownerModelNo,int ownerModelYear, int yearsOwned, String ownerName, int ownerId) {
        super(ownerBrand, ownerModelNo, ownerModelYear);

        this.yearsOwned = yearsOwned ;
        this.ownerName = ownerName;
        this.ownerId = ownerId;

        ArrayList<VehicleOwner> list = new ArrayList<VehicleOwner>();
        VehicleOwner owner1 = new VehicleOwner("Volvo", "XC60", 2014, 3, "Mary", 00011);
        VehicleOwner owner2 = new VehicleOwner("Subaru", "crosstrek", 2015, 2, "John", 00012);
        VehicleOwner owner3 = new VehicleOwner("Mercedes", "Eseries", 2016, 1, "Brandon", 00013);
        list.add(owner1);
        list.add(owner2);
        list.add(owner3);
    }
}

“缩短”这段代码的唯一方法是添加新对象而不为它们创建变量:

list.add(new VehicleOwner("Volvo", "XC60", 2014, 3, "Mary", 00011));
list.add(new VehicleOwner("Subaru", "crosstrek", 2015, 2, "John", 00012));
list.add(new VehicleOwner("Mercedes", "Eseries", 2016, 1, "Brandon", 00013));
