YES , wait and if we will say sum/product

hey everyone , i need your help about this exercice , i coudn't find the solution ''write a program in php console which finds the largest sequence of prime numbers such as their sum and product is a prime number ''

I am creating console application of top command (Linux) through java, but the results are only given for just the instant you run the program, I don't know how to delay or refesh the results with time to be like in Linux for the top command (the result appears continuously and dynamic like in linux )
