What is the output of this prg?
public class MyThread implements Runnable
myString = "Yes ";
public void run()
this.myString = "No ";
public static void main(String args)
MyThread t = new MyThread();
for (int i=0; i < 10; i++)
When I run this program ,it gives yes 9times,but in one of the mock exam it gives the answer "the ouput cannot be determined."
Am i correct?

You're right... (If you ave one "No" after your 9 "Yes", or ten "Yes")
Try to add loops (ex: i<1000)
You'll probably see "No" printed some times...
It will make more clear the assertion "the output cannot be determined".
In fact, the output can be defined by :
- A sequence of 10 words wille be printed : An indetermined number of "Yes" followed by zero or more "No".

General rule: Don't depend on the thread scheduler for behavior.
I agree. Here's the link:
