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. * * @author Arthur van Hoff * @version 1.21, 02/02/00 * @see java.lang.Thread * @since JDK1.0 */ public interface Runnable { /** * When an object implementing interface Runnable is used * to create a thread, starting the thread causes the object's * run method to be called in that separately executing * thread. *

* The general contract of the method run is that it may * take any action whatsoever. * * @see java.lang.Thread#run() */ public void run(); }
