Question: In the example below, the Student class overrides the getFood() method of the Person() class, and it uses super.getFood() to call the Person getFood() method
In the example below, the Student class overrides the getFood() method of the Person() class, and it uses super.getFood() to call the Person getFood() method before adding on to it. Here, a Person is associated with the food "Hamburger" and a Student is associated with "Hamburger" and "Taco".
Add another subclass called Vegan that inherits from the Student class. Add a Vegan contructor that takes a name as an argument and passes it to the super constructor. Override the getFood() method in Vegan to call the superclass getFood() but add a "No " in front of it and then say "but " and add a vegan food. Change Javier to a Vegan object in main() and try it out!
public class Person
{
private String name = null;
public Person(String theName)
{
name = theName;
}
public String getFood()
{
return "Hamburger";
}
public static void main(String[] args)
{
Person p = new Student("Javier");
System.out.println(p.getFood());
}
}
class Student extends Person
{
private int id;
private static int nextId = 0;
public Student(String theName)
{
super(theName);
id = nextId;
nextId++;
}
public String getFood()
{
String output = super.getFood();
return output + " and Pizza";
}
public int getId() {return this.id;}
public void setId (int theId)
{
this.id = theId;
}
}
