1. public class Test {
2. public static void main (String [] args) {
3. final Foo f = new Foo();
4. Thread t = new Thread(new Runnable() {
5. public void run() {
6. f.doStuff();
7. }
8. });
9. Thread g = new Thread() {
10. public void run() {
11. f.doStuff();
12. }
13. };
14. t.start();
15. g.start();
16. }
17. }
1. class Foo {
2. int x = 5;
3. public void doStuff() {
4. if (x < 10) {
5. // nothing to do
6. try {
7. wait();
8. } catch(InterruptedException ex) { }
9. } else {
10. System.out.println("x is " + x++);
11. if (x >= 10) {
12. notify();
13. }
14. }
15. }
16. }
What is the result?
A. The code will not compile because of an error on line 12 of class Foo.
B. The code will not compile because of an error on line 7 of class Foo.
C. The code will not compile because of an error on line 4 of class Test.
D. The code will not compile because of some other error in class Test.
E. An exception occurs at runtime.
F. x is 5
x is 6

Ans -- E
