Exercise $3$: Address

Implement a class Address. An address has a house number, a street, an optional apartment number, a city and a postal code. Supply two constructors: one with an apartment number and one without. Supply a print $($not a get$)$ method that prints the address with the street on one line and the city, state, and zip code on the next line.

Use the following tester class:

public class AddressTester

$1$

public static void main$($String$[$l args$)$

$($

Address al $=$ new Address $("1$b$","$B$$k$\_$m Sokak", "Ankara", $"06680")$;

Address a$2-$ new Address$("10","2","$ilek Sokak", "Istanbul", $"34714")$;

al$.$print $()$;

a$2.$print $()$;

$\}$
