hey thanks eduardo, I get it now..

Can anyone explain in more detail, still unable to understand fully..
Why false was printed on the console?

class Ticker extends Thread { public synchronized void run() { try { interrupt(); this.sleep(500); } catch(InterruptedException e) { System.out.println(interrupted()); } } } public class Test { public static void main(String[] args) { new Ticker().start(); } }

It says it will print false on the standard output.

01. import Outer.Inner.InnerMost;
02. import Outer.*;
03.
04. class Outer {
05. int i;
06. class Inner {
07. Inner() {i++;}
08.
09. class InnerMost extends Inner {
10. InnerMost() {i++; System.out.println(i);}
11. }
12. }
13. interface InnerInterface {
14. void doSomething();
15. }
16. }
17.
18. public class Test implements InnerInterface{
19.
20. public void doSomething() {
21. System.out.println("done");
22. }
23.
24. public static void main(String[] args) {
25. Inner im = new Outer().new Inner().new InnerMost();
26. }
27. }


The output is 3, Why is it not 2??

I get it now..

01. class BadObjectException extends Exception {}
02. class BadIndexException extends IndexOutOfBoundsException {}
03.
04. public class Test {
05.
06. public void doSomething() {}
07.
08. public void aMethod() {
09. try {
10. doSomething();
11. }catch(BadIndexException be) {
12. System.out.println("BadIndexException");
13. throw new BadIndexException(){};
14. }
15. }
16.
17. public void anotherMethod() throws BadObjectException{
18. try {
19. doSomething();
20. }catch(BadObjectException be) {
21. System.out.println("BadObjectException");
22. }
23. }
24.
25. public static void main(String[] args) throws BadObjectException{
26. Test t = new Test();
27. t.aMethod();
28. t.anotherMethod();
29. }
30. }

the output is that metnod anotherMethod() would not compile.
