Question about the task

Resolved

I'm pretty sure I created the size class

9.1. Self-encapsulate a field. Rewrite the incAverageGrade() method, using a setter and getter to access averageGrade.
9.2. Replace an array field with an object. Replace the int[] size array with an instance of a new Size type,
containing the following public fields: int height and int weight.
Declare a public Size class inside the Human class.
9.3. Encapsulate a field. Hide the company field in the Worker class. Add a corresponding setter and getter.
9.4. Replace a type code with a class.
9.4.1. Declare a public BloodType class inside the human package.
9.4.2. Add the following to the BloodType class: a constant private int code field, a private constructor that
has an int parameter and initializes the code field, and a corresponding getter.
9.4.3. Add static first(), second(), third() and fourth() methods to the BloodType class.
They should create and return BloodType objects with the correct code inside (1, 2, 3, and 4 respectively).
9.4.4. Use the new BloodType class in the Human class.
