Hello, I'm french and I don't find my problem on Ivor Horton java book
I make a windows for my command and before inert my command I must check if my Customer exists and if my product exist (do I must a search in my database)
If the client doesn't exist I call new Client(); but my problem is that my search for my product continue so i can register my new Customer. I wants stop the treatment 30seconds the time I register the customer and after continue my treatment
Thanks

I /think/ you're asking about Threads. Make your class implement Runnable and have it sleep for 30 seconds to implement the delay.
