Sure, here is a simple Java program that uses constructor overloading to achieve the desired functionality: ```java import java.util.ArrayList; public class Theatre { private ArrayList audienceNames; private double totalFare; // Default constructor public Theatre() { this.audienceNames = new ArrayList(); this.totalFare = 0.0; } // Constructor with audience name and ticket fare public Theatre(String audienceName, double ticketFare) { this(); // calling default constructor to initialize the ArrayList and totalFare this.audienceNames.add(audienceName); this.totalFare += ticketFare; } // Method to add new audience and their ticket fare public void addAudience(String audienceName, double ticketFare) { this.audienceNames.add(audienceName); this.totalFare += ticketFare; } // Method to get the total fare public double getTotalFare() { return this.totalFare; } // Method to get the audience names public ArrayList getAudienceNames() { return this.audienceNames; } public static void main(String[] args) { Theatre theatre = new Theatre(); theatre.addAudience("John Doe", 15.0); theatre.addAudience("Jane Doe", 20.0); System.out.println("Total fare: " + theatre.getTotalFare()); System.out.println("Audience names: " + theatre.getAudienceNames()); } } ``` In this program, we have a `Theatre` class with two constructors. The default constructor initializes the `audienceNames` ArrayList and `totalFare` to 0. The second constructor takes an audience name and ticket fare as parameters, adds the audience name to the `audienceNames` ArrayList and adds the ticket fare to `totalFare`. The `addAudience` method is used to add new audience and their ticket fare to the `audienceNames` ArrayList and `totalFare` respectively. The `getTotalFare` and `getAudienceNames` methods are used to get the total fare and audience names respectively. In the `main` method, we create a `Theatre` object and add two audiences using the `addAudience` method. Then we print the total fare and audience names.

The theatre wants to collect the names of all audience who visit the theatre and calculate the total amount collected as fare for the tickets from the audience. Write a Java program that implements the above using the concept of Constructor Overloading (Polymorphism)
