title: Limiting java application's memory and cpu usage
body: <p>Say, "run myApp.jar with cpu=800 and memory=1024"</p>
  
  <p>Ive been doing java programming for many years and it is an embarrasment to ask this question. I don't even know whether this is possible or not. And if so, how?</p>
  
  <p>What I just want know is if it is possible to set a java program's maximum memory and cpu usage. I suddenly thought of this because of I recently started developing mobile apps. I want to know how the app will behave on the device which has very limited memory and processor. </p>
  
  <p>I saw physics engines with demo apps that run on the browser or I can execute on my PC. What if I run them on a mobile device? Will the performance be the same? Rather than developing a sample mobile app to test the library's performance, I'd rather run it with a specific cpu and memory using my PC first.</p>
  
  <p>I tried googling by the way... all i found was monitoring and performance tuning. I may be using wrong keywords.</p>
