If people can execute arbitrary code in your app, they can already read your memory, and even if they couldn’t they could use java reflection to just turn off the private modifier
Accessibility modifiers are to do with maintainability. If you have internal implementation logic that should be hidden from a consumer you don’t want that consumer to have to know about things they shouldn’t be changing anyway.

So this looks like it’s based in Java code.
A public class means that any bit of Java code, including that injected by an attacker, can see and mess with the contents of that class.
A private class, in contrast, means that other bits of Java code are restricted to running the class’s predefined functions.
In theory it is supposed to help with the security of the data. In practice if an attacker gets to this point, you’ve got much bigger issues.
Private Vs public has nothing to do with security
