In-Depth Information
You can give a thread a name, either as a
String
parameter to the con-
structor or as the parameter of a
setName
invocation. You can get the
current name of a thread by invoking
getName
. Thread names are strictly
for programmer conveniencethey are not used by the runtime system-
but a thread must have a name and so if none is specified, the runtime
system will give it one, usually using a simple numbering scheme like
Thread-1
,
Thread-2
, and so on.
You can obtain the
Thread
object for the currently running thread by in-
voking the static method
THRead.currentThread
. There is always a cur-
rently running thread, even if you did not create one explicitly
main
itself
is executed by a thread created by the runtime system.
Exercise 14.1
: Write a program that displays the name of the thread
that executes
main
.
