Homework SourseWrite a class BasketballTeam encapsulating the concept of a
Write a class (BasketballTeam) encapsulating the concept of a team of basketball players. This method should have a single instance variable which is an array of basketball player objects. In addition to that class, you will need to design and a code a Playerclass to encapsulate the concept of a basketball player, assuming a basketball player has the following attributes: a name, a position, number of shots taken, and number of shots made.
In your Player class you should write the following methods:
A constructor taking a String for the name, a String for the position, an int for the number of shots taken, and an int for the number of shots made.
Accessor, mutator, toString, and equals methods.
A method returning the individual shooting percentage. Avg = Shots Made / Shots Taken. Hint: This method should return a double!!!
In your BasketballTeam class you should write the following methods:
A constructor taking an array of Player objects as its only parameter and assigning that array to the array data member of the class, its only instance variable.
Accessor, mutator, toString, and equals methods.
A method checking if all positions are different, returning true if they are, false if they are not.
A method returning the shooting percentage of the team. Team Shooting Percentage = Total Shots Made / Total Shots Taken Hint: This should return a double!!! Also, this is not the average of the the averages.
A method checking that we have a center (that is, the name of the position) on the team. If we do not have any return false; otherwise, it returns true;
A method returning void that sorts the array of Player objects in ascending order using the number of shots taken as the sorting key.
A method returning the array of Player objects sorted in ascending alphabetical order by name. Hint: Use compareTo method of the String class.
A method returning the name of the player with the most shots made.
A method returning the name of the player with the highest shooting average.
In your BasketballTeamClient class, when you test all your methods, you can hard-code five basketball Player objects. This client should call all 12 methods including the constructor for full credit.
When writing the Player class you should write a PlayerClient class that tests all its methods before integrating into BasketballTeam class.
