Given:
11. public static void parse(String str) {
12. try {
13. float f = Float.parseFloat(str);
14. } catch (NumberFormatException nfe) {
15. f = 0;
16. } finally {
17. System.out.println(f);
18. }
19. }
20. public static void main(String[] args) {
21. parse("invalid");
22. }
What is the result?
A. 0.0
B. Compilation fails.
C. A ParseException is thrown by the parse method at runtime.
D. A NumberFormatException is thrown by the parse method at runtime.

The answer is B . But i know where the problem is it with parse()method .

Welcome to CodeRanch!

We ask people to share where mock exam questions come from. Since you are new, I'll take care of that this time. It looks like it came from here.

Now on to your question, B is correct. It doesn't compile. Take a look where where f is declared. What is the scope? Where is it allowed to be referenced from?
