I am in an introductory java course and we just started learning about inheritance. I am working on a task that asks that we create a "Pet" superclass with name and age; and three subclasses, each with their own unique trait (I have chosen "Dog", "Cat", and "Bird"). After we have all these built, we are to create a Main class to test everything, and this is where I am running into problems. I am attempting to call the get
methods for these unique traits within Main
, but it seems to only find methods that are in the superclass.
Here is the Main class:
public class Kennel {
public static void main(String[] args) {
// Create the pet objects
Pet cat = new Cat("Feline", 12, "Orange");
Pet dog = new Dog("Spot", 14, "Dalmation");
Pet bird = new Bird("Feathers", 56, 12);
// Print out the status of the animals
System.out.println("I have a cat named " + cat.getName()
+ ". He is " + cat.getAge() + " years old."
+ " He is " + cat.getColor()
+ "When he speaks he says " + cat.speak());
System.out.println("I also have a dog named " + dog.getName()
+ ". He is " + dog.getAge() + " years old."
+ " He is a " + dog.getBreed()
+ " When he speaks he says " + dog.speak());
System.out.println("And Finally I have a bird named "
+ bird.getName() + ". He is " + bird.getAge() + " years old."
+ " He has a wingspan of " + bird.getWingspan() + " inches."
+ " When he speaks he says " + bird.speak());
}
}
Here is my superclass
abstract public class Pet {
private String name;
private int age;
// Constructor
public Pet(String petName, int petAge) {
this.name = petName;
this.age = petAge;
}
// Getters
public String getName() { return(this.name); }
public int getAge() { return(this.age); }
// Setters
public void setName(String nameSet) { this.name = nameSet; }
public void setAge(int ageSet) { this.age = ageSet; }
// Other Methods
abstract public String speak();
// toString
@Override
public String toString() {
String answer = "Name: " + this.name + " Age: " + this.age;
return answer;
}
}
And here is one of the subclasses (they all look the same and are having the same error)
public class Cat extends Pet {
private String color;
// Constructor
public Cat(String petName, int petAge, String petColor) {
super(petName, petAge);
this.color = petColor;
}
// Getters
public String getColor() { return(this.color); }
// Setters
public void setColor(String colorSet) { this.color = colorSet; }
// Other Methods
@Override
public String speak() { return "Meow!"; }
// toString
@Override
public String toString() {
String answer = "Name: " + super.getName() + " Age: "+super.getAge()
+ " Color: " + this.color;
return answer;
}
}
So what is happening is I can't get the main method to find the cat.getColor()
method, or any of the other ones unique to the subclasses.
