Runnable interface should be implemented by any
- * class whose instances are intended to be executed by a thread. The
- * class must define a method of no arguments called run.
- *
- * This interface is designed to provide a common protocol for objects that
- * wish to execute code while they are active. For example,
- * Runnable is implemented by class Thread.
- * Being active simply means that a thread has been started and has not
- * yet been stopped.
- *
- * In addition, Runnable provides the means for a class to be
- * active while not subclassing Thread. A class that implements
- * Runnable can run without subclassing Thread
- * by instantiating a Thread instance and passing itself in
- * as the target. In most cases, the Runnable interface should
- * be used if you are only planning to override the run()
- * method and no other Thread methods.
- * This is important because classes should not be subclassed
- * unless the programmer intends on modifying or enhancing the fundamental
- * behavior of the class.
