如何将其添加到数组列表中?
How can I add this to an arraylist?
我想将这些车辆添加到数组列表中,但必须通过 CourierManagementSystemImpl class 中的 addVehicle 方法来完成。我不知道该怎么做。
部分 public class CMSTestHarness:
//Arraylist
ArrayList<Vehicle> vehicles = new ArrayList<Vehicle>();
// Van(registrationNo, make, model, year, odometer, serviceInterval)
cms.addVehicle(new Van("v1", "Toyota", "Sienna", 1998, 0.0, 500.0));
cms.addVehicle(new Van("v2", "Volkswagen", "Routan S", 2009, 0.0, 1000.0));
CourierMangementSystemImpl 的一部分class
@Override
public void addVehicle(Van van) {
// TODO Auto-generated method stub
}
例如"vehicles"是CMS对象的字段。将参数传递给方法 addVehicle。在这个例子中,为了简单起见,我使用了字符串对象而不是 Van 对象。
public static void main(String[] args) {
CMS cms = new CMS();
// * This is Van object.
cms.addVehicle(new Van("v1", "Toyota", "Sienna", 1998, 0.0, 500.0));
cms.addVehicle(new Van("v2", "Volkswagen", "Routan S", 2009, 0.0, 1000.0));
for (String s : cms.getVehicles())
System.out.println(s);
}
public class CMS {
private ArrayList<String> vehicles = new ArrayList<String>();
public ArrayList<String> getVehicles() {
return this.vehicles;
}
public void addVehicle(String van) {
vehicles.add(van);
}
}
