Implement A Class Address: House Number And More ✓ Solved

Implement a class Address. An address has a house number, a street, an optional apartment number, a city, a state, and a postal code.

Implement a class Address with the following specifications: it should store a house number, street, optional apartment number, city, state, and postal code. Provide two constructors: one that includes the apartment number and one without. Implement a print method that displays the address with the street on one line and the city, state, and postal code on the next line. Also, include a method public boolean comesBefore(Address other) that returns true if this address's postal code comes before the other's when sorted numerically.

The class Address serves as a comprehensive model for managing postal address data in Java. It encapsulates the essential components of an address, including the house number, street, optional apartment number, city, state, and postal code. The class offers two constructors to facilitate flexible object creation: one that accepts all address elements including an apartment number, and another that omits the apartment number for addresses without additional units. This design choice accommodates diverse address formats and enhances usability.

The portrayal of the address is achieved through a dedicated print method, which outputs the street information on a single line followed by the city, state, and postal code on the subsequent line. This formatting ensures clarity and readability, mirroring conventional mailing address layouts. The formatting logic can be implemented using simple System.out.println statements, with conditional checks to include or exclude the apartment number as necessary.

A key functionality of the Address class is the ability to compare postal codes to determine address precedence. The comesBefore method accepts another Address object as a parameter. It compares this address’s postal code with the other’s and returns true if its postal code is numerically less, indicating it "comes before" in sorted order. This comparison facilitates operations such as sorting or organizing addresses in ascending postal code order.

Beyond address management, implementing classes with comparable properties is fundamental in object-oriented programming. Proper encapsulation, constructor overloading, and method design are essential to creating flexible and robust classes. The Address class exemplifies these principles, offering a straightforward yet functional model suitable for various mailing or address-tracking applications.
