Question about page 319 (Java OCA 8 Programmer I Study Guide)

[Cedric Georges]

I don't understand the last example of page 319 (the example which doesn't compile).

I tried the following code, which works fine:

package P10A_Exceptions;

public class C05_UnreachableCode {

    public static void main(String[] args) {
        
        try {
            raiseNoException();
        } catch (Exception exc) {
            System.out.println(exc.getMessage());
        }
        
    }
    
    public static void raiseException() throws Exception {
        raiseNoException();
    }
    
    private static void raiseNoException() {}
}

NetBeans give me the following output:

BUILD SUCCESSFUL (total time: 0 seconds)

Am I missign something?

Thank you for your help!

Yes, you are!

You are missing a (custom) checked exception. Don't forget that with Exception you can catch runtime exceptions as well. That's why the code compiles. But that's not what the study guide provides as an example. It uses a checked NoMoreCarrotsException and that's the difference with your code. So if you are too lazy to create a custom checked exception (like NoMoreCarrotsException) try changing all Exception occurences in your code with IOException and see what happens.

Hope it helps!
Kind regards,

PS. In Java we don't use underscores in package and class names.
