could you check my code? BC my teacher said I have to call a method (displayInfo() sections) but he said he don't tell me why(he pointed out the the area of every displayInfo() So i really don't know where should we edit). I really don't understand what I miss. ALSO I hope you can edit my code and feedback to me.

direction is this.

"

- An enumeration Month class consists of month constants from Jan to Dec.

- A name class has a first name and a last name; i.e., are the two instance variables of this class

- A Date class. Note that, other than the usual information for a calendar date i.e., private instance variables the day, the month (enum type), and the year; you have constructors, accessor and mutator methods. For the default constructor, initialize the date to 1st January 2023.

- A Height class has the same features as the Date class (constructors, accessor and mutator methods). Two private instance variables feet and inches. One important method is to convert the feet and inches and returns its equivalent value in meter.

A HealthProfile class has the same features as the Date class (constructors, accessor and mutator methods). Some important instance variables that you will see later in some UML diagram. You include also a few important methods related to the class; for example, get the maximum heart rate method, get the 3 minimum and the maximum of the targeted heart rate; compute and return the BMI; and a method to print out an object of this class."

Put all the classes in a Java file named it as YourName_A2.java (remove the word public from all classes)

(what is that mean? should I change all Public to private from my classes?)

input.txt should be like this

final output should be this

I did all UML in my code. Please help me to solve this code.
