How to access variables of a class from another file in JAVA

Question

I am new to java and I am trying to work a simple program. I have created a class and defined the variables like this

public class Animal {

    private String age;
    private String color;
    Breed breed;

    public String getAge() {
        return age;
    }

    public void setAge(String age) {
        this.age = age;
    }

    public String getColor() {
        return color;
    }

    public void setColor(String color) {
        this.color = color;
    }

    public Breed getBreed() {
        return breed;
    }

    public void setBreed(Breed breed) {
        this.breed = breed;
    }
}

class Breed {
    private String afador;
    private String afaird;
    private String aussiepom;

    public String getAfador() {
        return afador;
    }

    public void setAfador(String afador) {
        this.afador = afador;
    }

    public String getAfaird() {
        return afaird;
    }

    public void setAfaird(String afaird) {
        this.afaird = afaird;
    }

    public String getAussiepom() {
        return aussiepom;
    }

    public void setAussiepom(String aussiepom) {
        this.aussiepom = aussiepom;
    }
}

I want to access the variables in class "BREED" from ANOTHER file, with "animal.breed..." which does not work. How can I access the variables in the "BREED" class?? I am not sure if it is because I have the getter and setters in this file, kindly advise on the same.
