public interface Runnable
TheRunnable
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 calledrun
.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 classThread
. 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 subclassingThread
. A class that implementsRunnable
can run without subclassingThread
by instantiating aThread
instance and passing itself in as the target. In most cases, theRunnable
interface should be used if you are only planning to override therun()
method and no otherThread
methods. This is important because classes should not be subclassed unless the programmer intends on modifying or enhancing the fundamental behavior of the class.
