Question

Write a complete Java program with OO classes

The code should have:

1. A super class named Home
   • Properties
     • address
     • SF (this is the number of Square feet)
     • value (this is the dollar value of the home)
     • PPSF (price per square foot) you will calculate this in a method
   • Methods
     • Set and get methods for all properties
     • CalcPPSF - (PPSF is the value/SF)
2. A sub class named Condo, which has one more HOA property:
   • Property:
     • HOAfee (home owners association fee)
   • Methods
     • Set and get methods
3. A DemoCondo class, which is used to test your classes:
   • Create 10 Condo objects in an array (use a loop)
   • The addresses are 101 thru 110 Hardscrabble Drive
   • The SF are all 1150
   • The values are all $450,000
   • Use the calcPPSF method to fill the PPSF
   • The HOAfees are all $350
   • Output the contents of the array to the console after you have filled the array.

Answer 1

class Home // base class
{
   private String address;
   private int SF;
   private double value;
   private double PPSF;
  
   //set and get methods
   public void setAddress(String address)
   {
       this.address = address;
   }
   public void setSF(int SF)
   {
       this.SF = SF;
   }
   public void setValue(double value)
   {
       this.value = value;
   }
   public String getAddress()
   {
       return address;
   }
   public int getSF()
   {
       return SF;
   }
   public double getValue()
   {
       return value;
   }
   public double calcPPSF()
   {
       return value/SF;
   }
   public String toString()
   {
       return "\nHome Address : "+address +" Square Feet : "+SF +" value : $"+value +" price per square feet : $"+calcPPSF();
   }
}

class Condo extends Home // derived class
{
   private double HOAfee;
  
   public void setHOAFee(double HOAfee)
   {
       this.HOAfee = HOAfee;
   }
   public double getHOAFee()
   {
       return HOAfee;
   }
   public String toString()
   {
       return super.toString()+" HOA fee : $"+HOAfee;
   }
}

class DemoCondo
{
   public static void main (String[] args)
   {
      
       Condo[] condo = new Condo[10];
       int addr = 101;
      
       for(int i=0;i<10;i++)
       {
           condo[i] = new Condo();
           condo[i].setAddress(addr+" Hardscrabble Drive");
           addr++;
           condo[i].setSF(1150);
           condo[i].setValue(450000);
           condo[i].setHOAFee(350);
           condo[i].calcPPSF();
       }
      
       for(int i=0;i<10;i++)
       {
           System.out.println("Condo "+(i+1)+condo[i]);
       }

   }
}
