Question

1. Create a class named Lease with fields that hold an apartment tenant’s name, apartment number, monthly rent amount, and term of the lease in months. Include a constructor that initializes the name to “XXX”, the apartment number to 0, the rent to 1000, and the term to 12. Also include methods to get and set each of the fields. Include a nonstatic method named addPetFee() that adds $10 to the monthly rent value and calls a static method named explainPetPolicy() that explains the pet fee as folows: A pet fee of $10 is added to the monthly rent.

2. Create a class named TestLease whose main() method declares four Lease objects. Call a getData() method three times. Within the method, prompt a user for values for each field for a Lease, and return a Lease object to the main() method where it is assigned to one of main()’s Lease objects. Do not prompt the user for values for the fourth Lease object, but let it continue to hold the default values. Then, in main(), pass one of the Lease objects to the showValues() method that displays the data. Then call the addPetFee() method using the passed Lease object and confirm that the fee explanation statement is displayed. Next, call the showValues() method for the Lease object again and confirm that the pet fee has been added to the rent. Finally, call the showValues() method with each of the other three objects; confirm that two hold the values you supplied as input and one holds the constructor default values.

Code:-

// Lease.java
public class Lease
{
   private String tenantName;
   private int apartmentNumber;
   private double rent;
   private int termOfLease;
   Lease()
   {
       this.tenantName = "XXX";
       this.rent = 1000;
       this.apartmentNumber = 0;
       this.termOfLease = 12;
   }
   public String getTenantName()
   {
       return tenantName;
   }
   public void setTenantName(String tenantName)
   {
       this.tenantName = tenantName;
   }
   public int getApartmentNumber()
   {
       return apartmentNumber;
   }
   public void setApartmentNumber(int apartmentNumber)
   {
       this.apartmentNumber = apartmentNumber;
   }
   public double getRent()
   {
       return rent;
   }
   public void setRent(double rent)
   {
       this.rent = rent;
   }
   public int getTermOfLease()
   {
       return termOfLease;
   }
   public void setTermOfLease(int termOfLease)
   {
       this.termOfLease = termOfLease;
   }
   public void addPetFee()
   {
       this.rent += 10;
       explainPetPolicy();
   }
   public static void explainPetPolicy()
   {
       System.out.println("If you have pets, you should pay an extra rent of 10 dollars");
   }
}

// TestLease.java
import java.util.Scanner;
public class TestLease
{
   public static Lease getData()
   {
       Scanner in = new Scanner(System.in);
       Lease l = new Lease();
       System.out.print("Enter Tenant's Name: ");
       String name = in.nextLine();
       l.setTenantName(name);
       System.out.print("Enter Rent amount: ");
       double rent = in.nextDouble();
       l.setRent(rent);
       System.out.print("Enter Appartment Number: ");
       int number = in.nextInt();
       l.setApartmentNumber(number);
       System.out.print("Enter Term of lease: ");
       int term = in.nextInt();
       l.setTermOfLease(term);
       return l;
   }
   public static void showValues(Lease l)
   {
       System.out.println("Tenant's name: " + l.getTenantName());
       System.out.println("Rent Amount: " + l.getRent());
       System.out.println("Appartment Number: " + l.getApartmentNumber());
       System.out.println("Term of lease: " + l.getTermOfLease() + "\n");
   }
   public static void main(String args[])
   {
       Lease l1 = new Lease(), l2 = new Lease(), l3 = new Lease(), l4 = new Lease();
       l2 = getData();
       l3 = getData();
       l4 = getData();
       showValues(l1);
       l1.addPetFee();
       showValues(l1);
       showValues(l2);
       showValues(l3);
       showValues(l4);
   }
}
