Implement a class Address. An address has a house number, a street, an optional apartment number, a city, a state, and a postal code. Supply two constructors: one with an apartment number and one without. Supply a print method that prints the address with the street on one line and the city, state, and postal code on the next line. Supply a method public boolean comesBefore (Address other) that tests whether this address comes before another when the addresses are compared by postal code.

Answer:

public class Address {

   //Class feilds

   private int houseNumber;

   private int apartmentNumber;

   private String city;

   private String state;

   private int postalCode;

   private String street;

   // First Constructor with Apartment Number

   public Address(int houseNumber, int apartmentNumber, String city, String state, int postalCode, String street) {

       this.houseNumber = houseNumber;

       this.apartmentNumber = apartmentNumber;

       this.city = city;

       this.state = state;

       this.postalCode = postalCode;

       this.street = street;

   }

   // Second Constructor without Apartment Number

   public Address(int houseNumber, String city, String state, int postalCode, String street) {

       this.houseNumber = houseNumber;

       this.city = city;

       this.state = state;

       this.postalCode = postalCode;

       this.street = street;

   }

   public void printMethod(Address other){

       System.out.println("The street is "+other.street);

       System.out.println(other.city+", "+other.state+", "+other.postalCode);

   }

   public boolean comesBefore (Address other){

       if(other.postalCode > postalCode){

           return false; //If the postal code is greater, it means it comes after

       }

       else return true;// the postal code is less, so it comes before

   }

}

Explanation:

  • This is implemented with Java language
  • The fields as described in the question are first created
  • The two constructors as specified follows
  • The method printMethod accepts an Address object as a parameter and prints the street on the first line then  the city, state, and postal code on the next line
  • Finally the boolean method comesBefore receives an Address object as a parameter and compares the postalAdresses, if the postal address is greater, then the address comes after, else it comes before
