import java.io.*;
import java.awt.*;
public class Kyo extends Frame{
  public TextArea ta;
  
  public void Kyo()
  {
    initPage();
    fileReader("D:\\aa.txt");
  }
  public void initPage()
  {
    ta=new TextArea("",0,0,TextArea.SCROLLBARS_VERTICAL_ONLY);
    add(ta,"Center");
  }
  public void fileReader(String path)
  {
    File f=new File(path);
    StringBuffer sb=new StringBuffer();
    FileReader fr=null;
    BufferedReader br=null;
    try{
      fr=new FileReaderRose;
      br=new BufferedReader(fr);
      String line=br.readLine();
      while(line!=null)
      {
        sb.append(line);
        line=br.readLine();
      }
    }
    catch(Exception e){e.printStackTrace();
    }
    finally{
      if(fr!=null)try{fr.close();
      }catch(Exception e){
      }
      if(br!=null)try{br.close();
      }catch(Exception e){
      }
    }
    System.out.println("sb");
    ta.setText(new String(sb));
  }
  public static void main(String args[])
  {
    Kyo k=new Kyo();
    k.setBounds(100,100,600,400);
    k.setVisible(true);
  }
}
哪里出了错,System.out.println("aa");都不行
