Go to class Write review

Overview

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 repetition statements (for, while, do-while and for-each), the array data structure, methods and recursion.

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, although it is recommended that learners be comfortable with the topics addressed in AP Computer Science A: Java Programming.

We are looking forward to helping you explore this exciting new world!
