{  public static void main(String args[])
   {  String sentence[] = {"Java ", "is ", "an ", "object ", "oriented ",
                           "programming ", "language"};
      int numChars = 0;
      for (int i = 0; i < sentence.length; i++)
      {  System.out.print(sentence[i]);
         numChars += sentence[i].length();
      }
      System.out.println();
      System.out.println("Total chars: " + numChars);
      System.out.println("Total words: " + sentence.length);
      System.out.println("Avg.Chars: " + (double)numChars / sentence.length);
   }
