20.20.9

public Thread(ThreadGroup group, Runnable runObject)

throws SecurityException, IllegalThreadStateException

First, if group is not

null

, the

checkAccess

 method ( 20.21.4) of that thread

group is called with no arguments.

This constructor initializes a newly created

Thread

 object so that it has the

given

runObject

 as its separate run object, has a newly generated name, and

belongs to the thread group referred to by

group

 (but if

group

 is

null

, then the

new thread will belong to the same thread group as the thread that is creating the

new thread).

If

group

 is a

ThreadGroup

 that has been destroyed by method

destroy

( 20.21.11), then an

IllegalThreadStateException

 is thrown.

This constructor has exactly the same effect as the explicit constructor call

this(group, runObject, gname)

 ( 20.20.10) where

gname

 is a newly gener 

ated name. Automatically generated names are of the form

"Thread "+n

 where

n

is an integer.

20.20.10

public Thread(ThreadGroup group, Runnable runObject,

String name)

throws SecurityException, IllegalThreadStateException

First, if group is not

null

, the

checkAccess

 method ( 20.21.4) of that thread

group is called with no arguments; this may result in a

SecurityException

being thrown.

This constructor initializes a newly created

Thread

 object so that it has the

given

runObject

 as its separate run object, has the specified

name

 as its name,

and belongs to the thread group referred to by

group

 (but if

group

 is

null

, then

the new thread will belong to the same thread group as the thread that is creating

the new thread).

If

group

 is a

ThreadGroup

 that has been destroyed by method

destroy

( 20.21.11), then an

IllegalThreadStateException

 is thrown.

The priority of the newly created thread is set equal to the priority of the creat 

ing thread that is, the currently running thread. The method

setPriority

( 20.20.23) may be used to change the priority to a new value.

The newly created thread is initially marked as being a daemon thread if and

only if the thread creating it is a daemon thread. The method

setDaemon

( 20.20.25) may be used to change whether or not a thread is a daemon.
