Race Condition

A race condition occurs within a critical section when two or more tasks try to access and alter a shared resource simultaneously. As a consequence, the process changes to a state of inconsistency.

Question

Consider the below Java code.
import
public class Semaphore Demo
java.util.concurrent.Semaphore;
Semaphore binarySema= new Semaphore (1);
public static void main (String args[]) {
final SemaphoreDemo sema DemoObj= new Semaphore Demo ();
Thread td1= new Thread() (
public void run () {
}
}}
}
};
Thread td2= new Thread () {
@Override
public void run () {
sema DemoObj.testMutualExclusion ();
}
sema DemoObj.testMutualExclusion ();
tdl.start();
td2.start ();
private void testMutualExclusion () {
try {
binarySema.acquire();
System.out.println (Thread.currentThread().getName()+
"inside the region of mutual exclusive.");
Thread.sleep (1000);
} catch (InterruptedException e) {
ie.printStackTrace();
} finally (
System.out.println (Thread.currentThread().getName() +
"outside the region of mutual exclusive.");
What would be the output of the program?
