線程異常AWT EVENTQUEUE 1

Question

一切正常，直到當我按下我的任何按鈕時彈出錯誤。我正在按照指定的教程和做， 我不明白什麼是錯的。

「異常在線程 」AWT-EventQueue的-0「 java.lang.ArrayIndexOutOfBoundsException：1」

而這是代碼。

Answer 1

我對Farmacie的構造函數做了一些修改。我對行中第一個元素的分割進行了一些檢查。如果沒有空間，那麼它會在那裏失敗。否則你的代碼就可以。

private Farmacie() { 
    File f = new File("G:\\med.txt"); 
    ts = new TreeSet<Med>(); 
    String[] s, s1; 
    String ae; 
    if (f.exists()) { 
    try { 
     br = new BufferedReader(new FileReader(f)); 
     while ((l = br.readLine()) != null) { 
      s = l.split("_"); 

      s1 = s[0].split(" "); 
      String first = s1[0]; 
      String second = null; 
      if (s1.length > 1) 
       second = s1[1]; 

      med = new Med(first, second, s[1], s[2], s[3], s[4]); 
      ts.add(med); 
     } 
    } catch (IOException ioe) { 
     ioe.printStackTrace(); 
    } 
} else 
    System.out.println("Fisierul nu exista"); 

}
