Question

1. Design a class called Building. The class should keep the following information in the fields:

1. String address
2. double property_value

create several constructors including copy constructor , create accessor and mutator methods

       Part 2 (50 points)

2. Define interface Taxable which has one method getPropertyTax()

3. Design a class called Private_Property that extends Building and implements Taxable

It should have the following field : double value_of_improvements

Create a constructor for this class to include newly added fields.

The tax for the private property should be calculated as

0.02* (property_value - value_of_improvements)

4. Design a class called  Commercial_Property that extends Building and implements Taxable

It should have the following fields: double advertising_cost, double professional_expences

Create a constructor for this class.

The tax should be calculated as 0.02* (property_value - advertising_cost - professional_expences)

Part 3 (50 points)

5. Create a Demo class. In the main method create two variables of type Taxable. One should be instantiated as Private_Property and another as Commercial_Property. Demonstrate polymorphic behavior of the method getPropertyTax()

What you need to submit:

1. Complete code for all of the classes you created
2. Word file with
   1. Screenshot of copy constructor from part 1
   2. Screenshot of implementation of getPropertyTax() for each of the classes
   3. Screenshot of main method from the demo class
   4. Screenshot of execution results

Note: Could you plz go through this code and let me know if u need any changes in this.Thank You

// Taxable.java

public interface Taxable {

// Building.java

// Commercial_Property.java

public class Commercial_Property extends Building implements Taxable {

   @Override
   public double getPropertyTax() {
       return 0.02* (getProperty_value() - advertising_cost - professional_expences);

}

=======================================

// Demo.java

public class Demo {

   public static void main(String[] args) {

       double tax_Private_Property ,tax_Commercial_Property;
      
       Private_Property pp=new Private_Property("Park Street,Delhi",450000,34000);
       tax_Private_Property=pp.getPropertyTax();
       Commercial_Property cp=new Commercial_Property("Church Street,Banglore", 980000, 2500, 34000);
       tax_Commercial_Property=cp.getPropertyTax();
      
       System.out.println("Tax For Private Property :$"+tax_Private_Property);
       System.out.println("Tax For Commercial Property :$"+tax_Commercial_Property);
      
   }

}

=================================

output:

Tax For Private Property :$8320.0
Tax For Commercial Property :$18870.0

=====================Could you plz rate me well.Thank You
