How do I set this object's value? (Java 14)

I am learning Java for the first time, and in the tutorial I am watching (https://www.youtube.com/watch?v=grEKMHGYyns), the instructor writes this code:

    private Name personName;

    public Person(Name personName){
        this.personName = personName;
    }

Does anyone know what the object 'personName' of the constructor class 'Name' does?

How would I be able to set a value to 'personName' using the constructor 'Name' of class 'Name'?

I would show you the code for 'Name,' but I don't know how to set it up so that the object of 'Name' would hold any value.

Thanks for your help!

Name can be anything really. I haven't watched the video (wow, it is long) but in this context I guess it could contain a String value for that person's name.

Based on the information given I assume the class could look like this:

public class Name {
    private final String name;

    public Name(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }
}

Then to instantiate your Person, you need an instance of Name first:

Name name = new Name("AnyName");

With that you can create a new Person:

Person person = new Person(name);
