What is the difference between abstract methos and a method without any body i.e. only empty braces are given for methos but no body is there. Why cant we use empty method in the place of abstract method ? Pls explain the usage/advantages/disadvantages of both....Its urgent !!!
You can not call a abstract method, but you can call empty method. class with a abstract method, then it have to be a abstract class, sequencely you can instantiate a abstract class as well. Usually you provide empty method just because you want to use some other methods from parent class or implements a interface but you do not want to implements all of methods defined in interface definition.

I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
