Error at executing an external command! HElP!

Question

Hi, I must do as homework an app that tries to collapse the resources of a remote machine (procesor, memory, bandwidth and HDD), ok to collapse the bandwidth I wanted to make many pings with 65500 bytes, anyway, the code seems to work perfectly when doing this.
Runtime.getRuntime ().exec ("well here goes the ping");
then the bandwith gets at 100%, but I cant controll the amount of pings I am doing, for example I made a code and everytime a button is pressed it executes an infinite 65500 bytes ping. To be able to control the number of pings I made this:
Process P=Runtime.getRuntime ().exec ("well here goes the ping");
and the code executes without problem but when I monitor the bandwidth usage is on 0% usually it goes to 99% with 100 pings but now I made 120 and is still on 0% just for asigning the returned Process to a variable!
Please I need urgent help for this project.

Answer 1

ok, well this is my problem: I need to consume bandwidth. I made some pings with 65500 bytes, ok now:
If I do:
Runtime.getRuntime ().exec ("ping 192.168.0.2 /l 65500 /t");
it works and gets all the usage of the network (99%) with about 110 pings, now if I do:
Process P=Runtime.getRuntime ().exec ("ping 192.168.0.2 /l 65500 /t");
the bandwidth is on 0% event with more than 180 pings.
This pings are obviously concurrents. Any clue.
