java - 使用参数数组实例化对象列表

Question

我想像这样使用参数数组实例化一个对象列表:

String[] winnerData = ("Team_1#Team_2#...#Team_N").split("#");
List<Team> winners = new ArrayList();
for (String w : winnerData){
    winners.add(new Team(w));
}

我怎样才能干净地做到这一点？最好在一行中。

我不介意 winners/winnerData 是 List 还是 Array。

Answer 1

您可以使用 Stream API对于这样的需求。

String[] winnerData = ("Team_1#Team_2#...#Team_N").split("#");
// Create a Stream from the array of String
// For each String convert it as a Team using new Team(String)
// Convert the result as a List
List<Team> winners = Arrays.stream(winnerData)
    .map(Team::new)
    .collect(Collectors.toList());
