The document outlines the requirements for a class diagram of a rectangle class. It specifies one constructor accepting two integer parameters, functions for calculating and returning the area, and defines private integer variables for length, height, and area. Public and private access modifiers are denoted with + and - respectively.

1. Create a Class Diagram for a Rectangle class that has one constructor with two int parameters
length, width, a public int value return function get_area, one private void function
calculate_area, and three private int variables length, height, and area. Use + to denote public and
- to denote private.
