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);
}
谁能在这里帮助我,我要做的就是将对象中最后一个参数的所有值加在一起。
我下面的内容只是打印出最后一个对象的值(65)。
我会说这是我做错的小事,但是如果有人可以为我指出,那将很棒。
最佳答案
System.out.println("Total Points: " + points);

look here it should be total.
像这样改变。
System.out.println("Total Points: " + total);
要么
更改
points = ((Team) vec.elementAt(i)).getPoints();
total += points;
至
points += ((Team) vec.elementAt(i)).getPoints();
total = points;
