Java program that demonstrates the use of classes and constructors. Below is an example that creates an "Address class" with and without an apartment number. An image of the code and output of the program is attached.

Java code

import java.io.*;

public class Main{

public static void main(String args[]) throws IOException {

BufferedReader bufEntrada = new BufferedReader(new InputStreamReader(System.in));

//Variable Define

String r;

int hn;

String s;

int apt;

String c;

String st;

int pc;

hn = 0;

s = "";

apt = 0;

c = "";

st = "";

pc = 0;

Address address = new Address(0, "", 0, "", "", 0);

do {

//Data entry

System.out.println("With an apartment number or without? ");

System.out.println("(1) With ");

System.out.println("(2) without ");

r = bufEntrada.readLine();

r = r.toLowerCase();}

while (!(r.equals("1") || r.equals("2")));

// Function call

hn=address.HouseNumber(hn);

s=address.Street(s);

apt=address.AptNumber(apt);

c=address.City(c);

st=address.State(st);

pc=address.PostalCode(pc);

// Output

if (r.equals("1")) {

System.out.println("House number: "+hn);

System.out.println("Street name: "+s);

System.out.println("Apartment number: "+apt);

System.out.println("City: "+c);

System.out.println("State: "+st);

System.out.println("Postal code: "+pc);

}

else {

System.out.println("House number: "+hn);

System.out.println("Street name: "+s);

System.out.println("City: "+c);

System.out.println("State: "+st);

System.out.println("Postal code: "+pc);

}

while (!r.equals("n"));

}

// class address

class Address {

int HouseNumber;

String Street;

int AptNumber;

String City;

String State;

int PostalCode;

//Constructor address with and without apt number

Address (int HouseNum,String street,int aptNum, String city,String state, int postalCode) {

HouseNumber=HouseNum;

Street=street;

AptNumber=aptNum;

City=city;

State=state;

PostalCode=postalCode;

}

//Value returning

int HouseNumber(int hn){

return 594;

}

String Street(String s){

return "Wilmington";

}

int AptNumber(int apt){

return 1000;

}

String City(String c){

return "NEW YORK";

}

String State(String st){

return "NY";

}

int PostalCode(int pc){

return 2000;

}
