I disagree, it should show B, b, b instead.

Wait, isn't myString set to 'b' in getStringMethod?

The controller initializes myString to 'a' first.

I practiced a similar question, and I feel like the `getStringMethod` would return 'b' if called, but I'm confused about the order of execution here.

I'm not entirely sure, but I remember something about how private setters work. Could that change what gets displayed?

I think the first time the page loads, `myString` will be initialized to 'a', so that might affect the output.

I believe the output should be A, b, getMyString, but I’m not completely confident about the initial value of `myString`.

Hmm, I'm a bit unsure about this one. I know ITSI is an important Splunk app, but I'm not entirely clear on the deployment specifics. I'll have to think this through carefully.

I remember discussing the costs associated with licensing mobile apps and that it might be a disadvantage. But weren't there also other factors, like training employees?
