FRQ Teaching Classes
Lesson for class FRQs
Introduction
The AP Computer Science A exam includes four main types of Free Response Questions (FRQs):
- Methods and Control Structures
- Class
- Array/ArrayList
- 2D Array
Today, our focus is on attacking the Classes FRQ, which tests your understanding of object-oriented programming (OOP) concepts. This includes:
- Creating and manipulating classes
- Writing constructors
- Managing instance variables
- Implementing methods
- Understanding how objects interact in Java
Getting the first 4 points on ANY Classes FRQ
The key for tackling any classes frq, even if you don’t know how to solve the problem, is to have the right
- Instance Variables
- Attributes of an object (e.g.,
name,age).
- Attributes of an object (e.g.,
- Constructors
- Initialize objects and set instance variables.
- Methods
- Getters/Setters: Access and alter instance variables.
- Perform actions or computations related to the object.
Remembering to use the proper names, types, and encapsulations are key to getting these 4 points EASILY. Trystan will cover these in more detail in the prompt.
