Java code to increase cpu usage

How to increase CPU usage in Java?

You can modify the CPU load incurred by a Java program by inserting sleep statements (e.g. Thread. sleep() ) in your code, using variable delays to change the load. The simplest case would be a sleep statement in a loop, executed in a separate thread for each CPU core that you want to load.
