Chapter 3, Problem 13PE

Explanation of Solution

a.

Program code:

Lease.java

//define the class Lease

public class Lease

{

//declare class members

private static final double PET_FEE = 10;

private String tenantName;

private int apartmentNumber;

private double monthlyRent;

private int leasePeriod;

//Default constructor

public Lease()

{

//initialize the class members

tenantName ="XXX";

apartmentNumber =0;

monthlyRent = 1000;

leasePeriod =12;

}

//getters and setters

//define a method getTenantName()

public String getTenantName()

{

//return the variable tenantName

return tenantName;

}

//define a method setTenantName()

public void setTenantName(String tenantName)

{

//set the value of tenantName

this.tenantName = tenantName;

}

//define a method getApartmentNumber()

public int getApartmentNumber()

{

//return the variable apartmentNumber

return apartmentNumber;

}

//define a method setApartmentNumber()

public void setApartmentNumber(int apartmentNumber)

{

//set the value of apartmentNumber

this.apartmentNumber = apartmentNumber;

}

//define a method getMonthlyRent()

public double getMonthlyRent()

{

//return the variable monthlyRent

return monthlyRent;

}

//define a method setMonthlyRent()

public void setMonthlyRent(double monthlyRent)

{

//set the value of monthlyRent

this.monthlyRent = monthlyRent;

}

//define a method getLeasePeriod()

public int getLeasePeriod()

{

//return the variable leasePeriod

return leasePeriod;

}

//define a method setLeasePeriod()

public void setLeasePeriod(int leasePeriod)

{

//set the value of leasePeriod

this.leasePeriod = leasePeriod;

}

//define a method addPetFee()

public void addPetFee()

{

//adds $10

monthlyRent+=PET_FEE;

}

//define a method explainPetPolicy()

public static void explainPetPolicy()

{

//print the statement

System.out.println("Add $10 to rent as pet fee.");

}

}

Explanation:

The above snippet of code is used create a class “Lease”. The class contain different static methods for store the details of a lease. In the code,

• Define a class “Lease”
  • Declare the class members.
  • Define the constructor “Lease()” method.
    • Initialize the class members.
  • Define the “getTenantName()” method.
    • Return the value of the variable “tenantName”.
  • Define the “setTenantName()” method.
    • Set the value of the variable “tenantName”.
  • Define the “getApartmentNumber()” method.
    • Return the value of the variable “apartmentNumber”.
  • Define the “setApartmentNumber()” method.
    • Set the value of the variable “ApartmentNumber”.
  • Define the “getMonthlyRent()” method.
    • Return the value of the variable “MonthlyRent”.
  • Define the “setMonthlyRent ()” method.
    • Set the value of the variable “MonthlyRent”.
  • Define the “getLeasePeriod()” method.
    • Return the value of the variable “leasePeriod”.
  • Define the “setLeasePeriod()” method.
    • Set the value of the variable “leasePeriod”.
  • Define the “addPetFree()” method.
    • Set the value of “monthlyRent”.
  • Define the “explainPetPolicy()” method.
    • Print the statement.

TestLease.java

//import the packages

import java.text.NumberFormat;

import java.util.Scanner;

//define a class TestLease

public class TestLease

{

//define main() method

public static void main(String[] args)

{

//declare the objects of the class Lease

Lease lease1 = new Lease();

Lease lease2 = new Lease();

Lease lease3 = new Lease();

Lease lease4 = new Lease();

//Call three times getdata()

lease1 = getData();

lease2 = getData();

lease3 = getData();

System.out.print("Display info of tenants\n\n");

//Print info

showValues(lease1);

showValues(lease2);

showValues(lease3);
