JTree，很多條目

所以我習慣建立一個JTree加入DefaultMutableTreeNode的模型，但現在我有很多條目屬於1 JTree有沒有更簡單的方法來做到這一點可能像你做一個絲毫JList在那裏你可以指定一個String table[] = {};JTree，很多條目

所以這是直接從我的老JList的。該JTree應該是這樣的：

盾Hardners <父

因此，它應該是這樣的線

>>>彈道偏轉陣列<兒童
>>>爆炸潤版陣列<兒童

我已經在一個文件puting這一點，並分析它，並打印出像這樣的節點嘗試：

public class Env { 
    public static void main(String[] args) 
    {   
     try { 
      Scanner input = new Scanner(new File("data.txt")); 
      String line; 
      String sub; 
      while(input.hasNextLine()) 
      { 
       line = input.nextLine(); 

       String subline = line.replace('"', ' ').substring(11).replace("</b> </html> ,", " ").trim().replace(" ", "_"); 
       if(line.contains("<html>")){ 
        System.out.println("DefaultMutableTreeNode " + subline + " = new DefaultMutableTreeNode(" + line.replace(",", " ").trim() + ");"); 
       } 
      } 

     } catch (Exception e) {} 
    } 
}

之前，我寫完代碼有沒有做這個簡單的方法。

爲什麼不把它打成HTML，然後讓自己的魔法/轉換到正確的數據結構。 – 2012-01-01 19:23:28

@OmarIthawi：因爲它看起來不是一個有效的HTML文件，而是在某些行上帶有一些HTML標記的逗號分隔文件。 – 2012-01-01 19:25:02

當您想要在JList中使用數組時，您仍然必須創建一個循環來將條目添加到數組中。所以在這裏你的代碼有一個循環，直接將條目添加到TreeModel。你爲什麼認爲會有一個更簡單的方法？直接將數據添加到模型會更有效率（更短？），因爲您不需要使用數組的額外開銷。但要回答你的問題，沒有接受數組的構造函數。 – camickr 2012-01-01 19:28:18

我只能想到使用正則表達式來「簡化」字符串替換，但即使這是一個意見的問題。

import java.util.Scanner; 

public class TestFoo { 
    private static final String FILE_NAME = "data.txt"; 
    private static final String REGEX = "</?html>|</?b>|\"|,"; 

    public static void main(String[] args) { 
     Scanner scan = new Scanner(new File(FILE_NAME)); 
     while (scan.hasNextLine()) { 
     String line = scan.nextLine(); 
     String newLine = line.replaceAll(REGEX, "").trim(); 
     if (line.contains("html")) { 
      System.out.println("Default Mut: " + newLine); 
     } else { 
      System.out.println("\t" + newLine); 
     } 
     } 
    } 
}

你當然需要try/catch，並且不應該忽略catch塊。這也將刪除引號內的逗號，因此不理想。在線提供了可供下載的Java庫，可以非常乾淨地分析逗號分隔的文件。

沒有簡短的方式問題通過解析數據解決，如下圖所示，通過爲子節點添加else來解決。
