AP Computer Science A: Java Programming Classes and Objects
In this computer science course, you will learn the basics of programming in the Java language, and cover topics relevant to the AP Computer Science A course and exam.
This course will cover:
- objects and object-oriented design
- fields and visibility
- constructors, mutators and accessor methods
- the List interface
- method overriding
This course is for anyone interested in taking a first-level computer-programming course, particularly those who attend a school that does not provide a similar class.
No previous programming knowledge is needed, but it is recommended that learners be comfortable with the topics addressed in AP Computer Science A: Java Programming and AP Computer Science A: Java Programming Data Structures and Loops.
We are looking forward to helping you explore this exciting new world!
