I thought it was just for battery saving, guess I was wrong!

I thought MODE_PRIVATE was just for making data private, but I wonder if it affects performance in any way.

I feel like MODE_PRIVATE is definitely related to data privacy, but I can't recall if it has anything to do with battery usage or API levels.

I remember something similar from practice questions, but I'm not entirely sure if it also allows sharing with other apps.

I think MODE_PRIVATE is about keeping data secure within the app, so other apps can't access it.

Okay, I've got this. MODE_PRIVATE means the data stored using this mode is only accessible to the app that created it. No other apps can access it. That's the purpose of using it in the getPreferences() method.

I'm a bit confused by this one. I know MODE_PRIVATE has something to do with data storage, but I'm not sure of the exact purpose. I'll need to review my notes on Android shared preferences.

Hmm, this seems pretty straightforward. I think the key is understanding what MODE_PRIVATE does in the context of Android app development.

I'm pretty confident I know the answer to this one. MODE_PRIVATE ensures that the data stored using the getPreferences() method is kept private and secure within the app. Other apps won't be able to read or modify that data.

Okay, let me take a closer look at this. The graph has a smooth, continuous shape, so I'm leaning towards A or D. I'll eliminate the other options and then make my best guess.

Okay, I think I've got this. The key is to sort by the Age column first, and then by the Name column to get the desired order. I'll go with option C.

Hmm, I'm not entirely sure about this one. I'll need to think through the different options carefully.

I'm pretty confident this is an example of the Feedback principle. The confirmation message provides the user with immediate feedback that their purchase was successful.
