public String toString()

The returned value is a concatenation of the following seven strings:

  "Thread["

The current name of the thread ( 20.20.19)

  ","

The current priority of the thread ( 20.20.22), as a decimal numeral

  ","

The name ( 20.21.5) of the thread group ( 20.20.21) that contains this thread

  "]"

All literal characters mentioned above are from the ACSII subset of Unicode.

Overrides the

toString

 method of

Object

 ( 20.1.3).

20.20.12

public void checkAccess() throws SecurityException

If there is a security manager, its

checkAccess

 method ( 20.17.11) is called with

this

Thread

 object as its argument. This may result in a

SecurityException

being thrown in the current thread,.

This method is called by methods

stop

 of no arguments ( 20.20.15),

stop

 of

one argument ( 20.20.16),

suspend

 ( 20.20.17),

resume

 ( 20.20.18),

setName

( 20.20.20),

setPriority

 ( 20.20.23), and

setDaemon

 ( 20.20.25).

20.20.13

public void run()

The general contract of this method is that it should perform the intended action of

the thread.

The

run

 method of class

Thread

 simply calls the

run

 method of the separate

run object, if there is one; otherwise, it does nothing.

20.20.14

public void start()

throws IllegalThreadStateException

Invoking this method causes this thread to begin execution; this thread calls the

run

 method of this

Thread

 object. The result is that two threads are running con 

currently: the current thread (which returns from the call to the

start

 method)

and the thread represented by this

Thread

 object (which executes its

run

 method).
