java - 通过 vector 相加

Question

public static void main(String[] args)
    {
        Vector vec = new Vector();

        vec.add(new Team(1, "Manchester City", 38, 64, 89));
        vec.add(new Team(2, "Manchester United", 38, 56, 89));
        vec.add(new Team(3, "Arsenal", 38, 25, 70));
        vec.add(new Team(4, "Tottenham", 38, 25, 69));
        vec.add(new Team(5, "Newcastle", 38, 5, 65));

        int points = 0;
        int total = 0;

        for(int i = 0; i < vec.size(); i++)
        {
            points = ((Team) vec.elementAt(i)).getPoints();
            total += points;
        }
        System.out.println("Total Points: " + points);


    }

谁能帮我解决这个问题，我只想将对象中最后一个参数的所有值加在一起。

我下面的只是打印出最后一个对象的值 (65)。

我会说我做错了一些小事，但如果有人能为我指出，那就太好了。

Answer 1

 System.out.println("Total Points: " + points);
                                        |
                                        look here it should be total.

像这样改变。

 System.out.println("Total Points: " + total);

或

改变

points = ((Team) vec.elementAt(i)).getPoints();
total += points;

到

points += ((Team) vec.elementAt(i)).getPoints();
total = points;
