THE PACKAGE JAVA.LANG

20.20.5

public Thread(String name)

This constructor initializes a newly created

Thread

 object so that it has no sepa 

rate run object, has the specified

name

 as its name, and belongs to the same thread

group as the thread that is creating the new thread.

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

this(null, null, name)

 ( 20.20.10).

20.20.6

public Thread(Runnable runObject)

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 same thread group as the thread that is creating the new thread.

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

this(null, runObject, gname)

 ( 20.20.10) where

gname

 is a newly generated

name. Automatically generated names are of the form

"Thread "+n

 where

n

 is

an integer.

20.20.7

public Thread(Runnable runObject, String name)

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 same thread group as the thread that is creating the new thread.

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

this(null, runObject, name)

 ( 20.20.10).

20.20.8

public Thread(ThreadGroup group, 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 constructor initializes a newly created

Thread

 object so that it has no

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.

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

Thread(group, null, name)

 ( 20.20.10).
