      Character[] characterArray = {'H', 'E', 'L', 'L', 'O'};

      System.out.print("Array integerArray contains:%n");
      printArray(integerArray); // pass an Integer array 
      System.out.printf("%nArray doubleArray contains:%n");
      printArray(doubleArray); // pass a Double array
      System.out.printf("%nArray characterArray contains:%n");
      printArray(characterArray); // pass a Character array

   // generic method printArray
   public static <T> void printArray(T[] inputArray)
   {
      // display array elements
