Explanation / Answer

Answer:

PetData.java

public class PetData extends AnimalData {
private int idNum;
public void setID(int petID) {
idNum = petID;
return;
}
// FIXME: Add printAll() member function
/* Your solution goes here */
public void printAll() {
   super.printAll();
   System.out.print(", ID: " + idNum);
   return;
   }
}

AnimalData.java

public class AnimalData {
private int ageYears;
private String fullName;
public void setName(String givenName) {
fullName = givenName;
return;
}
public void setAge(int numYears) {
ageYears = numYears;
return;
}
// Other parts omitted
public void printAll() {
System.out.print("Name: " + fullName);
System.out.print(", Age: " + ageYears);
return;
}
}

BasicDerivedOverride.java

public class BasicDerivedOverride {
public static void main (String [] args) {
PetData userPet = new PetData();
userPet.setName("Fluffy");
userPet.setAge (5);
userPet.setID (4444);
userPet.printAll();
System.out.println("");
return;
}
}

Output:

Name: Fluffy, Age: 5, ID: 4444
