61. Output question 1.
class MyRunnable implements Runnable
{
public void run(){
for(int i=0;i<3;i++){
System.out.println("i="+i+"
,ThreadName="+Thread.currentThread().getName());
}
}
}
public class MyClass {
public static void main(String...args){
MyRunnable runnable=new MyRunnable();
System.out.println("start main() method");
Thread thread1=new Thread(runnable);
Thread thread2=new Thread(runnable);
thread1.start();
thread2.start();
System.out.println("end main() method");
}
Thread behaviour is unpredictable because execution of Threads depends on Thread scheduler,
start main() method will be the printed first, but after that we cannot guarantee the order of thread1, thread2 and main thread they might run simultaneously or sequentially, so order of end main() method will not be guaranteed.
Answer.
/*OUTPUT
start main() method
end main() method
i=0 ,ThreadName=Thread-0
i=0 ,ThreadName=Thread-1
i=1 ,ThreadName=Thread-0
i=2 ,ThreadName=Thread-0
i=1 ,ThreadName=Thread-1
i=2 ,ThreadName=Thread-1
