Solution

Here is a simple Java program that uses constructor overloading to implement the above scenario:

import java.util.ArrayList;

class Audience {
    String name;
    double fare;

    // Default constructor
    Audience() {
        this.name = "";
        this.fare = 0.0;
    }

    // Constructor with name parameter
    Audience(String name) {
        this.name = name;
        this.fare = 0.0;
    }

    // Constructor with name and fare parameters
    Audience(String name, double fare) {
        this.name = name;
        this.fare = fare;
    }
}

class Theatre {
    ArrayList<Audience> audienceList;
    double totalFare;

    // Constructor
    Theatre() {
        audienceList = new ArrayList<>();
        totalFare = 0.0;
    }

    // Method to add audience
    void addAudience(String name, double fare) {
        Audience audience = new Audience(name, fare);
        audienceList.add(audience);
        totalFare += fare;
    }

    // Method to display total fare
    void displayTotalFare() {
        System.out.println("Total fare collected: " + totalFare);
    }
}

public class Main {
    public static void main(String[] args) {
        Theatre theatre = new Theatre();
        theatre.addAudience("John Doe", 50.0);
        theatre.addAudience("Jane Doe", 60.0);
        theatre.displayTotalFare();
    }
}

In this program, we have two classes: Audience and Theatre. The Audience class has three constructors: a default constructor, a constructor that takes a name, and a constructor that takes a name and a fare. The Theatre class has a method addAudience that creates an Audience object and adds it to the audienceList. It also updates the totalFare. The displayTotalFare method prints the total fare collected. In the main method, we create a Theatre object and add two Audience objects to it, then display the total fare.
