需要将元素从网络传输到数组列表

Question

在成功抓取网络上的相关数据后，我需要将其传输到 ArrayList 中。

正如你在下面看到的，我打印了数据。现在我需要做的就是将其放入 ArrayList 中。有什么想法吗？

代码：

static String html = "http://games.espn.go.com/fba/playerrater?&slotCategoryId=1";

public static void main(String[] args) throws IOException, SQLException, InterruptedException {
    Document doc = Jsoup.connect(html).get();
    String title = doc.title();
   System.out.println(title);


    Iterator<Element> trSIter = doc.select("table.playerTableTable").iterator();
    while (trSIter.hasNext()) {
        Element  trEl = trSIter.next().child(0);
        Elements  tdEls = trEl.children();
        Iterator<Element> tdIter = tdEls.select("tr").iterator();
        boolean firstRow = true;
        while (tdIter.hasNext()) {

            Element tr = (Element)tdIter.next();
            if (firstRow) {
                firstRow = false;
                continue;
            }

        while (tdIter.hasNext()) 
        {  

            System.out.println("============================");
            Element tdEl = tdIter.next();
            String name = 
                    tdEl.getElementsByClass("playertablePlayerName").text();
            System.out.println("Name: "+name);
            String pointStr = 
                    tdEl.getElementsByClass("sortedCell").text();
            System.out.println("points: "+pointStr);
            //System.out.println(tdEl);
            Elements tdsEls = tdEl.select("td.playertableData");
            Iterator<Element> columnIt = tdsEls.iterator();
            boolean firstRow1 = true;


            while(columnIt.hasNext())
            {


                Element column = columnIt.next();
                 String stat1 =column.text();
                System.out.print(column.className()+":"+column.text()+","); 

输出：

Answer 1

创建一个包含名称、点数等变量的 Player 类。然后为每个玩家创建一个对象，最后将其添加到 ArrayList 中。

Player currentPlayer;
ArrayList<Player> players = new ArrayList<Player>();
// a lot of your code
while (tdIter.hasNext()) {  
    System.out.println("============================");
    Element tdEl = tdIter.next();
    currentPlayer = new Player();
    // instead of that:
    //String name = tdEl.getElementsByClass("playertablePlayerName").text();
    // do that:
    currentPlayer.mName = tdEl.getElementsByClass("playertablePlayerName").text();
    // the same with the rest of the gathered information
    // at the last line in this while loop
    players.add(currentPlayer);
}

谢谢沃伦！

我添加了一个开关以遍历所有元素
希望有些人能从我的问题中受益。感谢您的宝贵时间。

switch (tdCount++) {

                    case 1:
                        stat1 = Double.parseDouble(column.text());
                        break;
                    case 2:
                        stat2 = Double.parseDouble(column.text());
                        break;
                    case 3:
                        stat3 = Double.parseDouble(column.text());
                        break;
                    case 4:
                        stat4 = Double.parseDouble(column.text());
                        break;
                    case 5:
                        stat5 = Double.parseDouble(column.text());
                        break;
                    case 6:
                        stat6 = Double.parseDouble(column.text());
                        break;
                    case 7:
                        stat7 = Double.parseDouble(column.text());
                        break;
                    case 8:
                        stat8 = Double.parseDouble(column.text());
                        break;
                    case 9:
                        stat9 = Double.parseDouble(column.text());
                        break;
                    case 10:
                        stat10 = Double.parseDouble(column.text());
                        break;

                    }
                }

                PlayerBean pb = new PlayerBean(name, stat1, stat2, stat3,
                        stat4, stat5, stat6, stat7, stat8, stat9, stat10);
                playerlist.add(pb);
            }
