Hello! Today's lesson explores encapsulation in Java, a process that keeps sensitive class data safe through controlled access. Think of it as a safety box for class attributes. By implementing encapsulation, we can maintain the integrity of our data and the security of our code.

So, what is encapsulation? It's essentially data (attributes) and code arising from this data (methods) wrapped together to create a 'protective shell'. The class attributes become highly secure because they can only be accessed through the class methods. In other words, encapsulation keeps your data safe, ensuring your code is secure and reliable.

Java uses the private modifier to limit the visibility of class attributes. A private attribute can be accessed only within its specific class.

In the MyRobot class mentioned above, robotName is a private attribute, which implies it can be directly accessed only within the MyRobot class.

Getters and setters, also known as accessors and mutators, respectively, allow us to read and modify private attributes from outside the class.

Getters are used to obtain (or get) the value of a private attribute.
