Convert Double Value to Java String Using Append Method

The append method of the StringBuilder or StringBuffer objects accept a boolean or, char or, char array or, double or, float or, int or, long or, String value as parameter and adds it to the current object.

You can append the required double value to the method and retrieve a String from obtained StringBuffer (or, StringBuilder) objects.

      System.out.println("Enter a double value:");
      double d = sc.nextDouble();
      StringBuffer sb = new StringBuffer();
      sb.append(d);
      String result = sb.toString();
      System.out.println("The result is: "+result);
   }
}
