Exercise: Define a Class

Define a `Dog` class

Task Description:

Now it is time to create your own class. In this exercise you will be creating a class that represents a dog. Bellow are the steps you will need to take to create your first class.

Task List:

In IntelliJ, create a new project (we called ours creatingclass).

Inside the src directory, create a new package with the same name (again, we called ours creatingclass)

Right click the package and create a new class named Dog.

Create a class variable String dogType;.

Create a class variable String dogName;.

Create a class variable String dogColor;.

Create a class variable int dogAge;.

Create the constructor for the class that will set the class variables.

Create the accessor methods for each variable.

Create the mutator methods for each variable.

Override the class toString() methods: return "Dog type:" + dogType + " Dog name:" + dogName + " Dog Color:" + dogColor + " Dog age" + dogAge;

Task Feedback:

Nice work!

Solution

ND079 C1 L2 A06b Defining A Class Demo

Your code may be a bit different, but it should have the same variables, constructor, and methods, and it should have the toString method overridden.

Notice the variables have the private access modifier to ensure they are not directly accessible. While the methods access modifiers are public.

public class Dog {

    private String dogType;
    private String dogName;
    private String dogColor;
    private int dogAge;

    public Dog(String dogType, String dogName, String dogColor, int dogAge) {
        super();
        this.dogType = dogType;
        this.dogName = dogName;
        this.dogColor = dogColor;
        this.dogAge = dogAge;
    }

    public String getDogType() {
        return dogType;
    }

    public void setDogType(String dogType) {
        this.dogType = dogType;
    }

    public String getDogName() {
        return dogName;
    }

    public void setDogName(String dogName) {
        this.dogName = dogName;
    }

    public String getDogColor() {
        return dogColor;
    }

    public void setDogColor(String dogColor) {
        this.dogColor = dogColor;
    }

    public int getDogAge() {
        return dogAge;
    }

    public void setDogAge(int dogAge) {
        this.dogAge = dogAge;
    }

    @Override
    public String toString() {
        return "Dog type:" + dogType + " Dog name:" + dogName + " Dog Color:" + dogColor + "  Dog age" + dogAge;
    }
}
