It depends on the platform, but essentially uses it Runtime.getRuntime()to execute the corresponding command, to output it and analyze it for the necessary data.

If I am not mistaken Runtime.getRuntimefor the virtual machine, but not for the physical. What you are asking is getting information about a physical machine (which means a processor).
