Overview of Lab 7.1.4.9
In Lab 7.1.4.9, you will explore the concept of encapsulation in object-oriented programming. Encapsulation is an essential feature of OOP that allows you to bundle data and functions together within a class. It provides protection and control over the access to data, ensuring that it is only manipulated through predefined methods.
To start the lab, you will be provided with a pre-written class called “Rectangle” that represents a rectangle object. Your task is to complete the class by adding setter and getter methods for the length and width of the rectangle. These methods will encapsulate the data and control how it can be accessed and modified.
The setter methods should validate the input values for length and width to ensure they are positive numbers. If the input values are invalid, the setter methods should display an error message and not modify the data.
The getter methods should simply return the values of length and width.
Once you have implemented the setter and getter methods, you will create several instances of the Rectangle class and test the functionality of the encapsulation. You will manipulate the length and width of the rectangles by calling the setter methods, and retrieve their values using the getter methods.
By completing this lab, you will have a better understanding of encapsulation and how it can be used to control the access and manipulation of data within classes.
