java在文件末尾添加数据

在文件的末尾添加数据：

方法一：

public void appendToFile(String str)
{
      String filename = "d:\\append.txt";
      FileOutputStream stream;
      OutputStreamWriter writer;
      try
      {
         stream = new FileOutputStream(filename, true);
         writer = new OutputStreamWriter(stream);
         writer.write ("test");
         writer.write(str);
         writer.close();
         stream.close();
      }
      catch(Exception e)
      {
            e.getStackTrace ();
      }
}

方法二：

RandomAccessFile fos=new RandomAccessFile("test.xml);
fos.seek(fos.length());将指针移动到文件尾
fos.writeBytes("\n"+shr);
fos.close();
