Complete the weekly labs based on the following: Write the code for each lab assignment

Complete the weekly labs based on the following: Write the code for each lab assignment. The lab is to be submitted in a single zip file in the online course shell, which must contain all .java files, along with any additional files that may be necessary for your project to run (ex: text files). Any and all written answers must be entered into the online course shell with the submission of the attached lab assignment. 1. Create a class named Horse that contains data fields for the name, color, and birth year. Include get and set methods for these fields. Next, create a subclass named RaceHorse, which contains an additional field that holds the number of races in which the horse has competed and additional methods to get and set the new field. Write an application that demonstrates using objects of each class. Save the files as Horse.java, RaceHorse.java, and DemoHorse.java.

The objective of this assignment is to demonstrate the principles of object-oriented programming in Java through the creation of a base class and a subclass, along with a demonstration application. The assignment entails designing a Horse class with fundamental attributes, extending it with a RaceHorse subclass to include racing-specific data, and finally, developing a demo application that showcases the instantiation and utilization of both classes.

Students are required to submit all relevant Java source files in a single compressed ZIP archive. These files include Horse.java, RaceHorse.java, and DemoHorse.java. Additional project resources, such as text files, should be included if necessary for program operation. The students must also input any written responses or explanations into the online course shell, accompanying their code submission.

Design and Implementation

The Horse class will serve as the foundational class, encapsulating three primary data fields: name, color, and birthYear. Each of these fields should be private and accessed or modified via public getter and setter methods. For example, getName(), setName(), getColor(), setColor(), getBirthYear(), and setBirthYear() methods.

The RaceHorse class will extend the Horse class, inheriting its properties and behaviors. This subclass should introduce an additional private data field to store the number of races in which the horse has participated. Corresponding getter and setter methods should be provided to access and manipulate this new attribute.

The DemoHorse class will contain the main method, within which objects of Horse and RaceHorse will be instantiated. The demonstration should showcase setting and retrieving attribute values, and possibly, displaying the full details of each object to verify that the classes function as intended. This class serves as a practical example of inheritance, encapsulation, and object interaction in Java.

Example Class Structures



public class Horse {


private String name;


private String color;


private int birthYear;


// Constructor


public Horse(String name, String color, int birthYear) {


this.name = name;


this.color = color;


this.birthYear = birthYear;


}


// Getters and setters


public String getName() {


return name;


}


public void setName(String name) {


this.name = name;


}


public String getColor() {


return color;


}


public void setColor(String color) {


this.color = color;


}


public int getBirthYear() {


return birthYear;


}


public void setBirthYear(int birthYear) {


this.birthYear = birthYear;


}


}





public class RaceHorse extends Horse {


private int racesParticipated;


public RaceHorse(String name, String color, int birthYear, int racesParticipated) {


super(name, color, birthYear);


this.racesParticipated = racesParticipated;


}


public int getRacesParticipated() {


return racesParticipated;


}


public void setRacesParticipated(int racesParticipated) {


this.racesParticipated = racesParticipated;


}


}





public class DemoHorse {


public static void main(String[] args) {


Horse horse = new Horse("Thunder", "Black", 2015);


RaceHorse raceHorse = new RaceHorse("Storm", "Brown", 2012, 25);


// Display information


System.out.println("Horse Details:");


System.out.println("Name: " + horse.getName());


System.out.println("Color: " + horse.getColor());


System.out.println("Birth Year: " + horse.getBirthYear());


System.out.println("\nRaceHorse Details:");


System.out.println("Name: " + raceHorse.getName());


System.out.println("Color: " + raceHorse.getColor());


System.out.println("Birth Year: " + raceHorse.getBirthYear());


System.out.println("Number of Races: " + raceHorse.getRacesParticipated());


// Modify attributes


horse.setName("Lightning");


raceHorse.setRacesParticipated(30);


// Display updated information


System.out.println("\nUpdated Horse Details:");


System.out.println("Name: " + horse.getName());


System.out.println("\nUpdated RaceHorse Details:");


System.out.println("Name: " + raceHorse.getName());


System.out.println("Number of Races: " + raceHorse.getRacesParticipated());


}


}

Conclusion

This assignment highlights key concepts in Java such as encapsulation, inheritance, and object interaction. Proper design and implementation of classes enable effective code reuse and clarity. The demonstration not only confirms correct functionality but also illustrates how inheritance facilitates extending base class functionalities with specific features pertinent to subclasses.
