public static void writeFile(String fileName, String fileContent) 
{  
  try 
  {  
    File f = new File(fileName);  
    if (!f.exists()) 
    {   
      f.createNewFile();  
    }  
    OutputStreamWriter write = new OutputStreamWriter(new FileOutputStream(f),"gbk");  
    BufferedWriter writer=new BufferedWriter(write);    
    writer.write(fileContent);  
    writer.close();  
  } catch (Exception e) 
  {  
    e.printStackTrace();  
  }
}

public static String readFile(String fileName)
{  
  String fileContent = "";  
  try 
  {   
    File f = new File(fileName);  
    if(f.isFile()&&f.exists())
    {   
      InputStreamReader read = new InputStreamReader(new FileInputStream(f),"gbk");   
      BufferedReader reader=new BufferedReader(read);   
      String line;   
      while ((line = reader.readLine()) != null) 
      {
