Test if file exists

I'm trying to open a file in android like this :

  try
   {
      FileInputStream fIn = context.openFileInput(FILE);
      DataInputStream in = new DataInputStream(fIn);
      BufferedReader br = new BufferedReader(new InputStreamReader(in));
      if(in!=null)
          in.close();
   }
   catch(Exception e)
   {  }

, but in case the file does not exists a file not found exception is thrown . I'd like to know how could I test if the file exists before attempting to open it.
