23.32 + * The <code>Runnable</code> interface should be implemented by any
23.33 + * class whose instances are intended to be executed by a thread. The
23.34 + * class must define a method of no arguments called <code>run</code>.
23.35 + * <p>
23.36 + * This interface is designed to provide a common protocol for objects that
23.37 + * wish to execute code while they are active. For example,
23.38 + * <code>Runnable</code> is implemented by class <code>Thread</code>.
23.39 + * Being active simply means that a thread has been started and has not
23.40 + * yet been stopped.
23.41 + * <p>
23.42 + * In addition, <code>Runnable</code> provides the means for a class to be
23.43 + * active while not subclassing <code>Thread</code>. A class that implements
23.44 + * <code>Runnable</code> can run without subclassing <code>Thread</code>
23.45 + * by instantiating a <code>Thread</code> instance and passing itself in
23.46 + * as the target. In most cases, the <code>Runnable</code> interface should
23.47 + * be used if you are only planning to override the <code>run()</code>
23.48 + * method and no other <code>Thread</code> methods.
23.49 + * This is important because classes should not be subclassed
23.50 + * unless the programmer intends on modifying or enhancing the fundamental
23.51 + * behavior of the class.
