How to do it...

Follow these steps to implement the example:

1. Create a class named Task and specify that it implements the Runnable interface:

        public class Task implements Runnable {

2. Implement the run() method. Create a loop with 1,000,000 steps, and in each step, do some mathematical operations with an integer variable:

        @Override         public void run() {           int r;           for (int i=0; i<1000000; i++) {             r=0;             r++;             r++;             r*=r;           }         }

3. Implement the main class of the example by creating a class named Main and adding the main() method to it:

        public class Main {            public static void main(String[] args) {

4. Create 1,000 threads to execute 1,000 task objects and wait for their finalization, controlling the total execution time:

 Thread threads[]=new ...
