    As far as I am aware, there is no built-in library in Java that can provide this information across different operating systems. The reason is that the way processes and their CPU usage are managed is highly dependent on the operating system.

  • I’m afraid not. The closest you can come is the totalCpuDuration() method of the ProcessHandle.Info class, but that isn’t the percentage of CPU being used.

  • You need to use native calls to the operating system to get this information. I'm sure this question has already been asked previously. have you searched Stack Overflow?.
