    1.31 +/**
    1.32 + * The <code>Runnable</code> interface should be implemented by any
    1.33 + * class whose instances are intended to be executed by a thread. The
    1.34 + * class must define a method of no arguments called <code>run</code>.
    1.35 + * <p>
    1.36 + * This interface is designed to provide a common protocol for objects that
    1.37 + * wish to execute code while they are active. For example,
    1.38 + * <code>Runnable</code> is implemented by class <code>Thread</code>.
    1.39 + * Being active simply means that a thread has been started and has not
    1.40 + * yet been stopped.
    1.41 + * <p>
    1.42 + * In addition, <code>Runnable</code> provides the means for a class to be
    1.43 + * active while not subclassing <code>Thread</code>. A class that implements
    1.44 + * <code>Runnable</code> can run without subclassing <code>Thread</code>
    1.45 + * by instantiating a <code>Thread</code> instance and passing itself in
    1.46 + * as the target.  In most cases, the <code>Runnable</code> interface should
    1.47 + * be used if you are only planning to override the <code>run()</code>
    1.48 + * method and no other <code>Thread</code> methods.
    1.49 + * This is important because classes should not be subclassed
    1.50 + * unless the programmer intends on modifying or enhancing the fundamental
    1.51 + * behavior of the class.
