Advanced Placement Computer Science A (also called AP Java or AP Comp Sci A) is an AP Computer Science course and examination offered by the College Board to high school students as an opportunity to earn college credit for a college-level computer science course. AP Computer Science A is meant to be the equivalent of a first-semester course in computer science. The AP exam currently tests students on their knowledge of Java.

AP Computer Science AB, which was equivalent to a full year, was discontinued following the May 2009 exam administration.

AP Computer Science A emphasizes object-oriented programming methodology with an emphasis on problem solving and algorithm development. It also includes the study of data structures and abstraction, but these topics were not covered to the extent that they were covered in AP Computer Science AB. The Microsoft-sponsored program Technology Education and Literacy in Schools (TEALS) aims to increase the number of students taking AP Computer Science classes.

Topics covered by the course include:

Historically, the AP exam used several programs in its free-response section to test students' knowledge of object-oriented programs without requiring them to develop an entire environment. These programs were called Case Studies.

This practice was discontinued as of the 2014-15 school year and replaced with optional labs that teach concepts.

Case studies were used in AP Computer Science curriculum starting in 1994.

The Big Integer case study was in use prior to 2000. It was replaced by the Marine Biology case study.

The Marine Biology Case Study (MBCS) was a program written in C++ until 2003, then in Java, for use with the A and AB examinations. It served as an example of object-oriented programming (OOP) embedded in a more complicated design project than most students had worked with before.
