Here's an approach to implementing the three classes and the main program for your basketball player project:

Height Class:

Create a Height class with two instance variables: feet and inches.

Make the class immutable by not providing setter methods.

Implement a constructor that accepts feet and inches as parameters and creates a Height object.

Implement a toInches method that returns the total height in inches $($feet $*12+$ inches$).$

Implement a toString method that returns a string representation of the height in the format $"$X$\text{'}$Y$\text{'}\text{'}"$ where X is feet and Y is inches $($normalized if Y $>=12).$

Player Class:

Create a Player class with three instance variables: name $($string$),$ height $($of type Height$),$ and age $($integer$).$

Make the class immutable by not providing setter methods.

Implement a constructor that accepts name, height, and age as parameters and creates a Player object.

Main Program:

In the main program, create a list of Player objects, each representing a basketball player.

Calculate the average age of all players by summing up the ages and dividing by the number of players.

Initialize variables to keep track of the tallest player and their height.

Iterate through the list of players:

Check if the player's age is less than or equal to the calculated average age.If yes, compare their height to the current tallest player and update the tallest player if needed.

After iterating through all players, you'll have the tallest eligible player.

Print the name and height of the tallest eligible player.

This approach ensures that you have well$-$defined classes for Height and Player, and the main program handles the logic of finding the tallest player within the specified age criteria.

Remember to create instances of the classes and populate the player list with player objects before running the logic in the main program.
