错误其他没有，如果

Question

我在我的程序中有一个错误：else without if但是，我认为我有一个完美的if和else。我认为这个问题是因为我有大量的try/catches。我只有一个错误，那就是它。我的继承人代码：

 BufferedReader br = null; 
    try { 
     br = new BufferedReader(new FileReader("pass.txt")); 
    } catch (FileNotFoundException ex) { 
     JOptionPane.showMessageDialog(rootPane,"Please run setup. Password file not found"); 
     Logger.getLogger(NewJFrame.class.getName()).log(Level.SEVERE, null, ex); 
    } 
     try { 
      StringBuilder sb = new StringBuilder(); 
      String line = null; 
      try { 
       line = br.readLine(); 
      } catch (IOException ex) { 
       Logger.getLogger(NewJFrame.class.getName()).log(Level.SEVERE, null, ex); 
      } 

      while (line != null) { 
       sb.append(line); 
       sb.append(System.lineSeparator()); 
       try { 
        line = br.readLine(); 
       } catch (IOException ex) { 
        Logger.getLogger(NewJFrame.class.getName()).log(Level.SEVERE, null, ex); 
       } 
      } 
      String cool = sb.toString(); 
      char[] input = jPasswordField1.getPassword(); 
      if (input.equals(cool)); { 
       JOptionPane.showMessageDialog(rootPane,"Password is correct!"); 

      } finally { 
      try { 
       br.close(); 
      } catch (IOException ex) { 
       Logger.getLogger(NewJFrame.class.getName()).log(Level.SEVERE, null, ex); 
      } 
     } 
     } catch (FileNotFoundException ex) { 
      Logger.getLogger(NewJFrame.class.getName()).log(Level.SEVERE, null, ex); 
     } finally { 
      try { 
       br.close(); 
      } catch (IOException ex) { 
       Logger.getLogger(NewJFrame.class.getName()).log(Level.SEVERE, null, ex); 
      } 
    } 
    char[] input = jPasswordField1.getPassword(); 

}              

Answer 1

我没有看到你发布的代码的任何else（也许你遗漏了一些代码），但错误可能是在这里：

if (input.equals(cool));

删除;

Answer 2

移除多余的分号这里

if (input.equals(cool));
