About this course

Skip About this course

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:

  • classes
  • objects and object-oriented design
  • fields and visibility
  • constructors, mutators and accessor methods
  • encapsulation
  • interfaces
  • 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!
