What is wrong here?

[arun mahajan]

Hello,
I was making following simple program and it is giving eror:
java.lang.IllegalMonitorStateException: current thread not owner
If I use sleep insteand of wait() method it works.
What could be the reason? Pl help.
regards,
Arun :roll:

 
public class testThread extends Thread
{
boolean flag=true;
public void run()
{
System.out.println("Starting Run method....");
while(flag)
{
read();
}
}
public void read()
{
try
{
System.out.println("Let me sleep....");
wait(5*1000);
notifyAll();
System.out.println("Let me awake....");
}
catch(Exception e)
{
System.out.println("Error: "+e);
}
}
public static void main(String[] args)
{
System.out.println("Starting....");
testThread xx = new testThread();
xx.start();
}
}

Oh I am sorry. I found the error. Methods are not synchronized. Thanks any way.
