Hi Dominic,

If you make a method to return the value of the color, you should make your variable private, otherwise your method to get the value of color isn't very useful if you set the variable public.

Look at the example below, Person contains two attributes: firstName and lastName. These are initialized with the constructor whenever an instance of this class is created.

public class Person{
    private String firstName;
    private String lastName;

    public Person(String firstName, String lastName){
        this.firstName = firstName;
        this.lastName = lastName;
    }

    public String getFirstName(){
        return this.firstName;
    }

    public String getLastName(){
        return this.lastName;
    }
}

After we defined the constructor, we can now create a Person object:

Person me = new Person("John", "Smith");

We can then access the values of firstName and lastName of our newly created Person object using the get methods:

System.out.printf("Hello! My first name is: %s, my last name is: %s.", me.getFirstName(), me.getLastName());

This will print out: Hello! My first name is: John, my last name is: Smith.
