oliver, just stop posting.
oliver_lundag -4 Newbie Poster
why?
kvprajapati 1,826 Posting Genius Team Colleague
why?
- Don't talk with old or solved threads.
- Use BB code tags
- Read all posts of a thread and then put your comment.
sillyboy 43 Practically a Master Poster
4. stop hi-jacking threads
5. don't post complete code (at least initially)
kvprajapati commented: Thanks. +7

I am the one who made that code. just want to share it. why are you complaining... I just want to share... instead of saying that thing to me why don't you try to help those people who needs help. I think you are selfish.
karamjeet2004 0 Newbie Poster
thanks for the code
i am new to java
it took me a week to understand
but anyway thanks

Thanks,
Mark this thread as "Solved" if you get appropriate solution.

Wrong!
You are just spoon-feeding the OP, is that what you want?
I can say you: it's against Daniweb's homework policy.
Ever heard of this? I would say: No.
And look, you're even so poor that you still can't use code tags correctly to post your crap, is it too difficult for you to just type the following on your keyboard?
[code=Java] // Your rubbish here
[/code]
(Reminder on how to use code tags: http://www.daniweb.com/forums/announcement9-3.html)
>I think you are selfish.
Well, do you think that? I don't.
He at least tries to help people learn, not to give them away a solution where they don't benefit from (in sense of: they don't learn anything from just copying that).
You don't have to think you're superior now because you've given away some code.
If you want to share this code, then I would rather go for a code snippet (to mention: you can't have problems with the code tags there, except in the comment(s)).
>instead of saying that thing to me why don't you try to help those people who needs help.
Do you think you've helped the OP then?
By just providing your code?
I don't think that.
My understanding of the word 'help' is that the OP will be able to do it himself the next time, and that he won't have to beg for some code.
>I am the one who made that code.
And what can we conclude then?
