Answer Posted / jitender arora
Corrected my previous answer:
public class A implements Runnable {
/**
* @author jeetendra.arora
* @param args
*/
A(){
System.out.println("Constructor..");
}
public static void main(String[] args) {
A a = new A();
Thread t1 = new Thread(a);
t1.start();
Thread t2 = new Thread(a);
t2.start();
}
public void run(){
System.out.println("Thread
started.."+Thread.currentThread().getName());
Thread.currentThread().getName();
methodA();
}
private boolean inUse = false;
public void methodA(){
while(!inUse){
inUse = true;
System.out.println
("processing...."+Thread.currentThread().getName());
try{
Thread.currentThread().sleep(3000);
}
catch (Exception e){
System.out.println("Exp");
}
System.out.println
("complete.."+Thread.currentThread().getName());
}
inUse = false;
}
}
