  public static void main(String args[]) {    

    FileOutputStream out = null;       

    try {          

      out = new FileOutputStream("test.txt");      

      out.write(122);       

    }   

    catch(IOException io) {             

      System.out.println("IO Error.");    

    }         

    finally {      

      out.close();   

    }  

  } 

}

and given that all methods of class FileOutputStream, including close(), throw an IOException, which of these is true?
