Resource summary
Polymorphism
is meant to make changes in the method definition of the derived classes, and have those changes apply to methods written in the base class
Example:
Annotations:
people[0] = new Undergraduate("Cotty, Manny", 4910, 1); people[1] = new Undergraduate("Kick, Anita", 9931, 2); people[2] = new Student("DeBanque, Robin", 8812); people[3] = new Undergraduate("Bugg, June", 9901, 4);
people[0] = new Undergraduate("Cotty, Manny", 4910, 1); people[1] = new Undergraduate("Kick, Anita", 9931, 2); people[2] = new Student("DeBanque, Robin", 8812); people[3] = new Undergraduate("Bugg, June", 9901, 4);
Say we ran the writeOutput() method on each of these. Which writeOutput is used?
The one in the class that was USED TO CREATE THE OBJECT.
Not necessarily "person", but "Undergraduate" and "Student."
THIS IS A FORM OF DYNAMIC BINDING!
THERES A WHOLE PROJECT BASED ON EXAMPLES FOR POLYMORPHISM!
