The purpose of the Thread.run() method is to execute code in a separate, dedicated thread. Calling this method directly doesn’t make
sense because it causes its code to be executed in the current thread.
To get the expected behavior, call the Thread.start() method instead.
Noncompliant Code Example
Thread myThread = new Thread(runnable);
myThread.run(); // Noncompliant
Compliant Solution
Thread myThread = new Thread(runnable);
myThread.start(); // Compliant
