閱讀文本文件到JTable中

Question

我試着從一個文本文件的一些數據導入到我的JTable .. 我寫了一些代碼來做到這一點：

JMenuItem Open = new JMenuItem("Open gegevens"); 
    Open.addActionListener(new ActionListener() { 
     public void actionPerformed(ActionEvent arg0) { 


      readTXT(); 


     } 
    }); 

    mnNewMenu.add(Open); 

public void readTXT(){ 



      try{  
       String readLine = null; 
       File file = new File("Resultaten.txt"); 
       FileReader reader = new FileReader(file); 
       BufferedReader bufReader = new BufferedReader(reader); 

       while((readLine = bufReader.readLine()) != null) { 
        String[] splitData = readLine.split("; "); 
        System.out.println(splitData.length); 
        String match= splitData[0]; 
        String set= splitData[1]; 
        String spelertje1= splitData[2]; 
        String gamesspeler1= splitData[3]; 
        String streep= splitData[4]; 
        String gamesspeler2= splitData[5]; 
        String spelertje2= splitData[6]; 
        String setwinnaartje= splitData[7]; 
        String matchwinnaartje= splitData[8]; 

        model.addRow(new Object[] { match,set, spelertje1, gamesspeler1, 
          streep, gamesspeler2, spelertje2, setwinnaartje, matchwinnaartje }); 
        System.out.println("okidokii"); 

       } 



       reader.close(); 
      } 
      catch(IOException e){ 
       JOptionPane.showMessageDialog(null, "Error"); 
     e.printStackTrace(); 

      } 


    } 

在我看來這應該工作，但還沒有我得到這個：

其實我明白這個問題..絃樂splitdata只有一個字符串來容納。但我intialised它白衣分割方法..

我txtfiles看起來是這樣的：

這是我以前寫的代碼我JTable中txtfile：

public void writeTXT(){ 
      try { 


      File file = new File("Resultaten.txt"); 

       PrintWriter os = new PrintWriter(file); 
       System.out.println(os); 
       os.println(""); 




       for (int row = 0; row < table.getRowCount(); row++) { 


        for (int col = 0; col < table.getColumnCount(); col++) { 
         //os.print(table.getColumnName(col)); 
         os.print(";"); 
         os.print(table.getValueAt(row, col) + "\t") 

         System.out.println("ok"); 

        } 

        os.println(""); 
       } 
       os.close(); 
       System.out.println("Done!"); 
      } catch (IOException e1) { 
       // TODO Auto-generated catch block 
       e1.printStackTrace(); 

     } 


     } 

對於你的知識，使用這種方法時jtable沒有什麼事......

感謝您的好評

Answer 1

String splitdata只有一個字符串。但我初始化它白衣分裂的方法..

那麼，爲什麼你粘貼所有代碼相關的表？您的問題是將文本拆分爲令牌。

根據你的代碼，它看起來像你寫了一個semi-colon and a tab character，但它看起來像拆分使用semi-colon and a space character，所以你沒有得到你期望的令牌。

你可以寫一個簡單的SSCCE來測試這一點：

公共類主要

{ 
    public static void main(String[] args) 
    { 
     String text = ";\tone;\ttwo;\tthree;\tfour"; 

     for (String word: text.split("; ")) 
//  for (String word: text.split(";\t")) 
      System.out.println(word); 
    } 
} 

在您發表的問題只發布的相關信息，瞭解問題。

Answer 2

根據異常和您的代碼似乎splitData的長度小於9

編輯：（由於OP接受第一部分）

確保您的文件劃界「 ;」並具有所需的長度。
