Let me tell you right now: nope, they cannot. But Let’s kick this off with why and how this works in our favorite programming language.

First things first, what are private variables anyway? Well, my friend, a private variable is just like any other variable except that it can only be accessed within the class where it was declared. This means that if you try to access a private variable from another class or even from a subclass of its parent class, Java will throw a fit and refuse to compile your code.

Now inheritance this is when one class inherits properties and behavior from another class. In Java, we use the extends keyword to create a subclass that inherits from a superclass. This means that all of the fields and methods in the parent class are now available for use by the child class.

But here’s where things get interesting private variables cannot be inherited! That’s right, Even if you extend a class with private variables, those variables will not be accessible from your subclass. This is because Java doesn’t allow direct access to private fields outside of their own class.

So why can’t we inherit private variables? Well, let me explain it like this imagine that you have a parent class called “Person” with a private variable called “age”. If you create a subclass called “Student”, and try to access the age variable from within Student, Java will throw an error because the age variable is not accessible outside of its own class.

But wait! What if we make the age variable protected instead? This would allow us to inherit it in our subclasses, right? Well… sorta. Protected variables can be accessed by both their parent and child classes, but they cannot be accessed from other unrelated classes. So while this might seem like a solution at first glance, it’s not always the best option for encapsulation or abstraction.

So what should we do instead? Well, if you need to access private variables in your subclass, you can create getter and setter methods that allow you to manipulate those variables indirectly. This is a good practice because it allows us to maintain the integrity of our code by preventing direct access to sensitive data.
