Question

I got the same problem that sun_fade has which is related to running a program behind the scene ..... this the topic that sun_fade issued
((((((Am currently working on a small java project which run through a unix terminal ... my program take some time (about 20 seconds ) to do some checking and calculations... My question is that when I run this program I need to wait for this 20 seconds or what ever my program take and after that I will get the result ... what I want is to make the control go back to system so i can issue some commands and do some stuff and when the program is done I will get the result .... exactly when you issue >>>> httpd start and you press enter ....
Thanks in advance )))))
and some guys answers that we can do such a thing by using a Threads ..... so what I want is just a simple program that type a message like "" hello Dude """ after 2 minutes ,showing this message on the terminal and also during this time the control is back to the system so I can issue some commands and after time elapsed the message will appear .....
for example---
bash:- java hellodude
bash:- // and I can do what I want issuing commands what ever ..... etc
when 2 minutes elapsed

You're still not explaining your problem well at all.

Hello dude
bash:- There are two ways two do that. You've already been told one. I'm not going to tell you the other one because I don't like your attitude.
I will tell you this, though: That's probably a stupid thing to do. I don't want some output from a previous command popping out in the middle of other work I'm doing. If I really do, I'll explicitly say so with &.
Actually, now that I think about it, the second way might not work anyway.
There's a third way though, but it will be heinously ugly. The only sensible way to do that is to use &. A more sensible way would be, as sabre suggested, to use a separate terminal
