setters

Setters are methods in programming that allow you to safely modify the value of an object’s property. Think of them as controlled access points: instead of directly changing a property, you use a setter method to update it. This approach helps manage and validate data, ensuring that any change maintains the object’s integrity. For example, if you have a 'height' property, a setter can ensure that only positive numbers are assigned. Setters work alongside getters, which retrieve property values, providing a structured way to control how data within objects is accessed and modified.
