how I transfer/use vars or/and methods from a Thread subclass -to-> the class of main

how I transfer/use vars or/and methods from a Thread subclass -to-> the class of main() and vice versa ?

a subclass like":
class MyThread extends Thread
{
may contain getters / setters run from main() to get values from subclass ?

When you create an instance of your Thread in the main() the main() will have access to the public methods of your thread object.

public static void main(String[] args)
{
   MyThread myThread = new MyThread();

   myThread.setSomeValue("blah");
   System.out.println( myThread.getSomeValue() );
   
   myThread().start();
}

If I have:
public String getAd() { return ad; }
in a getter and
ad var
setup via
String ad = input.nextLine();
in run()
running in main()(other class) the
x=advt.getAd();
it will work ? where is error ? when call the
x=advt.getAd();
prior or after advt.start();

???

Forget writing threads for now. Get yourself a decent Java tutorial and learn the basics first including how to create instances and how to call methods.

I know that well and did it but on threads no compile?
C:\JavaAdv\Lesson6\Assign61>javac Advertisement.java
Advertisement.java:41: cannot find symbol
symbol : variable x
location: class Advertisement
public boolean getAd() { return x; }
^
1 error

There is no "x" variable in scope within the getAd method. Again, I have to agree with r...x as this is a very basic aspect of Java that you need to know before messing with threads. You would benefit greatly by studying a basic Java tutorial.

basically I want when thread
class Advertisement extends Thread
{
public void run()....
exits alone
class TestAdvt
{
public static void main (String[] args)
{
get terminated, but when exit with advt.interrupt();
...
catch (InterruptedException e)
{
break;
...
continue running the threed from beginning ?

[lse123]

you mean to transfer vars/methods between classes is the same as normal, in case of Thread classes ?

[lse123]

must be different since now we have run(), what if a var get it's value from the run() ?

You are not making any sense. The run method is void.
Do read the Java basics tutorial. If you already read it(like you claimed above) the read it again because you clearly missed some of the basics.
