Comment on Tutorial : Transient vs Volatile modifiers in Java By Reema sen
Updated example to better show Thread T2 showing the latest updated value in variable 'testValue'. And this example does work!!

public class VolatileExmaple {
public static void main(String[] args) {

VolatileTest instanceOfVolatileExample = new VolatileTest();

Thread t1 = new Thread(instanceOfVolatileExample, "T1");
Thread t2 = new Thread(instanceOfVolatileExample, "T2");

t1.start();
t2.start();

}
}

------------------

public class VolatileTest implements Runnable {

private volatile int testValue;

public void run() {
for (int i = 0; i < 20; i++) {
try {
//System.out.println(Thread.currentThread().getName() + ": " + i);
int randomInt = new Random().nextInt(20);
if (Thread.currentThread().getName().equalsIgnoreCase("T1")) {
testValue = new Random().nextInt(20);
System.out.println("T1 - Set Test value: " + testValue);
} else if (Thread.currentThread().getName().equalsIgnoreCase("T2")) {
if (randomInt < 9) {
try {Thread.sleep(100); } catch (Exception ignore) {}
}
System.out.println("T2 - Read Test value: " + testValue + "\n");
}

Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
