Finding Number of Cores in Java

How can I find the number of cores available to my application from within Java code?

Look at the Runtime class's methods.

Finding Number of Cores in Java

int cores = Runtime.getRuntime().availableProcessors();

If cores is less than one, either your processor is about to die, or your JVM has a serious bug in it, or the universe is about to blow up.

Or a divine power is giving you a sign not to make your application dependent on the number of cores. :)
