Constructs a new
Thread
with the specified
name
and uses the
run
method of the specified
target
.
public
Thread(ThreadGroup group, Runnable target)
Constructs a new
Thread
in the specified
ThreadGroup
and uses
the
run

ThreadGroup
later.
public
Thread(ThreadGroup group, Runnable target, String name)
Constructs a new
THRead
in the specified
THReadGroup
with the
specified
name
and uses the
run
method of the specified
target
.
public
THRead(ThreadGroup group, Runnable target, String name, long
stacksize)
Constructs a new
THRead
in the specified
ThreadGroup
with the
specified
name
and uses the
run
method of the specified
tar-
get
. The
stackSize
parameter allows a stack size for the thread
to be suggested. The values appropriate for a stack size are
completely system dependent and the system does not have
to honor the request. Such a facility is not needed by the vast
majority of applications, but like most things of this nature,
when you do need it, it is indispensable.
Classes that have only a
run
method are not very interesting. Real
classes define complete state and behavior, where having something
execute in a separate thread is only a part of their functionality. For ex-
ample, consider a print server that spools print requests to a printer.
Clients invoke the
print
method to submit print jobs. But all the
print
method actually does is place the job in a queue and a separate thread
then pulls jobs from the queue and sends them to the printer. This al-
lows clients to submit print jobs without waiting for the actual printing
to take place.
