Hi,
I have an Object that gets locked by various threads via a synchronized block. Something Like:
class MyThread extends Thread{
public void run(){
synchronized(someObject){
// do stuff to some Object
}
}
}
Is there an easy way to have an another instance of MyThread examine "someObject" and see if it is locked by another thread? This way I could tell the user something like "waiting for locked resource..."
Thanks
Hi,
Try with the following code, it stars two threads
which share the same object "MyThread" as shown below :
code:
class MyThread extends Thread {
boolean wait = false ;
public void run(){
callMe();
}
public synchronized void callMe() {
while( wait == true )
{
System.out.println(" Waiting for releasing the lock");
try{
wait();
}
catch( InterruptedException e ) { }
} System.out.println(" Locked ");
wait = true;
notifyAll();
}
public static void main( String[] args ) {
MyThread t = new MyThread();
new Thread(t).start();
new Thread(t).start(); }}
Hope this will help you
Anil.
