@ Michael Dunn WHY? Am new in java and this forums, i posted because it has been difficult for me to resolve on my own and i believe i could get solution when i come here, why discouraging me this way? Pleas if you of any simple way for me to handle my problem i will appreciate it.
Because it is rude to ask several fora and not let each other know. Somebody might be going to a lot of effort, here or on the other forum, to provide you with an answer, which you have already received. You are causing that person to waste their time.
Look at it from (say) my point of view. you post this question on (let's say) Stack Overflow, and here, at 9 a.m. At 9:30, you get an answer on SO. At 9:45, I see your question here, without an answer. I don't know, but your question intrigues me. I spend 30 minutes researching your question writing code samples, experimenting, and crafting what I believe is a wonderful, clear, and epic answer, and post it at 10:15.
My time has been completely wasted, as you already have your answer. I could have spent that 30 minutes of my time helping others who need it.
We are not opposed to you using every resource to get an answer. We simply ask that you let us know. That way, if at 9:45 I see you had posted to SO, I could check that thread and see you have your answer, and not spend my time finding an answer you already have.
There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors
