I recently answered this question for another student.
You can see that answer here:

Setters and getters allow you to store and retrieve variable data with the added benefit of being able to also manipulate that data in the process.
For example, you could do some validation or store the value as all lowercase or perform some math function(s) or do some sort of formatting.

Stay safe and happy coding!
