How does and what happend when we try 5 == 5?? with a java 1.4 version?? I tried with 1.5 and it gave me true as the o/p.

Anyone here to explain this?

It's going to happen the same thing in java 1.4 or 1.5, java is designed to be backwards compatible. In both cases the == compares if the primitives have the same value, or if the references both point to the same instances of the object (to know if two different instances both represent the same object you must override and use the .equals method defined in Object)
 
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
