Course Update ? make fos and oos local variable

We can see in the vide Craig put the fos and oos variable inside the auto-closeable block like this:

try (
       FileOutputStream fos = new FileOutputStream("Treet.ser");
       ObjectOutputStream oos = new ObjectOutputStream(fos);
) {
//.......
} catch(IOException ioe) {
//.......
} finally {
// fos and oos variable can't be accessed 
}

but if we access the variable inside the "finally" block it will give an error because fos and oos variable are declared in the try block. I have try it on the Intellij IDEA IDE. So I head to google and find the answer https://stackoverflow.com/questions/2854144/problem-with-scopes-of-variables-in-try-catch-blocks-in-java. We should do it like this:

// Local variable scope
FileOutputStream fos;
ObjectOutputStream oos;
try (
       fos = new FileOutputStream("Treet.ser");
       oos = new ObjectOutputStream(fos);
) {
//.......
} catch(IOException ioe) {
//.......
} finally {
// do something with fos and oos
}

Correct me if i am wrong :) Craig Dennis

UPDATE

I think with this try-with-resource block we don't have to use the finally block because it will be closed regardless of whether the try statement completes normally or abruptly. https://docs.oracle.com/javase/tutorial/essential/exceptions/tryResourceClose.html.

And also the code above is wrong, we can't make local variable and assign it inside the try statement. https://stackoverflow.com/questions/13836486/why-is-declaration-required-in-javas-try-with-resource. So the correct syntax is:

try (
       FileOutputStream fos = new FileOutputStream("Treet.ser");
       ObjectOutputStream oos = new ObjectOutputStream(fos);
) {
//.......
} catch(IOException ioe) {
//.......
}
