AP计算机科学A：Java编程

你将学到什么

课程概况

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 includes a broad view of computer operation, the global impact of computing, and then introduces Java programming concepts including variables, selection and object-oriented design.

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