What letters are written to the standard output with the following code?


1.����class Unchecked {
2.�������public static void main(String[] args) {
3.����������try {
4.�������������method();
5.����������} catch(Exception e) {}
6.�������}
7.�������static void method() {
8.����������try {
9.�������������wrench();
10.������������System.out.println("a");
11.���������}catch(ArithmeticException e) {
12.������������System.out.println("b");
13.���������}finally {
14.������������System.out.println("c");
15.���������}
16.���������System.out.println("d");
17.������}
18.������static void wrench() {
19.���������throw new NullPointerException();
20.������}
21.���}
Select all valid answers(correct answers are blue):
a.
����"a"
b.����"b"
c.����"c"
d.����"d"
Here's what I thought... that both c and d would be printed, because the program would execute line 16 after the last finally block. Why is this so?

Thanks in advance,
Barbara

No. It doesn't print d.
Because. method wrench() throws a NullPointerException which is not caught by any of the following catch blocks. So, after executing finally block, we still have a uncaught exception. In such cases, the method execution is terminated. Program control is passed back to line #5 after printing "c".

Oh, duh!
Thanks... sometimes I just can't see it through my own eyes. That was a big help.
