Question

Here is the complete code of my problem.I�ve CADEntityImpl.java extending AtreeObject.java .CadPointImpl.java extending CADEntityImpl.java.CADPointImpl.java uses few constants of IEntitiesConstants.java and Main Program is ServerPartImpl.java. Here is the complete code.

Answer 1

Well Mr. Dheeraj - nice to know that you are still endevoring to gather knowledge. I guess that is required, especially as you come from a Computer Mechnaic background.
Well then, allow me to give a few bits of wisdom (don't worry they are free). It would rather be greatly appreciated if you could stop embarrasing yourself in public by trying to catch my attention.
If you require my assistance (which I am sure you would be), just write to me :> (I am sure that by now you must have got my mail address by heart). I must assure you that I never turn down pleas for help from commoners like yourself.
However, I can sympathise with you on the count of the pang that you must be feeling while trying to graduate from a mechanic to a Master (which I am sure your limited capability is not permitting you).
However, as is my duty, I always help commoners like you when I so deine to :>
Your Lord
