THE PACKAGE JAVA.LANG

java.lang.Thread

20.20

PrimeRun p = new PrimeRun(143);

new Thread(p).start();

Every thread has a name, which is a

String

, for identification purposes. More

than one thread may have the same name. If a name is not specified when a thread

is created, a new name is generated for it.

Every thread that has not yet been stopped belongs to a thread group ( 20.21).

A thread can always create a new thread in its own thread group. To create a

thread in some other thread group requires the approval of the

checkAccess

method ( 20.21.4) of that thread group, which forwards the decision to the secu 

rity manager ( 20.17.11).

20.20.1

public final static int MIN_PRIORITY = 1;

The constant value of this field is

1

, the smallest allowed priority for a thread.

20.20.2

public final static int MAX_PRIORITY = 10;

The constant value of this field is

10

, the largest allowed priority value for a

thread.

20.20.3

public final static int NORM_PRIORITY = 5;

The constant value of this field is

5

, the normal priority for a thread that is not a

daemon.

20.20.4

public Thread()

This constructor initializes a newly created

Thread

 object so that it has no sepa 

rate 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, null, 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.
