  // Decimal Value in the 12345.68 format

  // By rounding the last digit

  DecimalFormat dec = new DecimalFormat("###.##");

  System.out.println(dec.format(12345.6789)); 



  // Decimal Value in the 12345.679 format

  // By rounding the last digit

  dec = new DecimalFormat("###.###");

  System.out.println(dec.format(12345.6789)); 



  // Decimal Value in the 12345.7 format

  // By rounding the last digit

  dec = new DecimalFormat("###.#");

  System.out.println(dec.format(12345.6789));

  }

}
