Note 2: Citation(s) for a "Lesson" refer to the "Lesson Text" elements and associated "Activities" within the course, unless otherwise noted. The "Instructional Video" components are supplements designed to introduce or re-enforce the main lesson concepts, and the Lesson Text contains full details. AP Course Description This course teaches students the fundamentals of the Java programming language and covers all required topics defined by the College Board's AP Computer Science A course description. AP Lab Requirements The AP Computer Science A course must include a minimum of 20 hours of hands-on structured-lab experiences to engage students in individual or group problem solving. This course easily meets and exceeds the 20-hour minimum lab requirement with hands-on lesson exercises and chapter activities. In addition, coverage of both new example labs and the old GridWorld lab is provided for teachers to use as needed. Magpie Lab (recommended starting in ) Picture Lab (recommended starting in ) Elevens Lab (recommended starting in ) GridWorld Case Study (no longer required, but available for use if desired) See "Work with Me" sections within lessons and "Chapter Activities" in each chapter.

8 Standard Java Library Notes 1. Students are expected to understand the operator precedence rules of the listed operators. 2. The increment/decrement operators ++ and -- are part of the AP Java subset. 3. Students need to understand the short circuit evaluation of the && and operators. 4. Students are expected to understand truncation towards 0 behavior as well as the fact that positive floating-point numbers can be rounded to the nearest integer as (int)(x + 0.5), negative numbers as (int)(x - 0.5). 5. String concatenation + is part of the AP Java subset. Students are expected to know that concatenation converts numbers to strings and invokes tostring on objects. 6. User input is not included in the AP Java subset. 7. Both arrays of primitive types (e.g., int[], int[][] ) and arrays of objects (e.g., Student[], Student[][] ) are in the subset. 8. Students need to understand that 2-dimensional arrays are stored as arrays of arrays. For the purposes of the AP CS A Exam, students should assume that 2-dimensional arrays are rectangular (not ragged) and the elements are indexed in row-major order. Students are expected to be able to access a row of a 2-dimensional array, assign it to a 1-dimensional array reference, pass it as a parameter, and use loops (including for-each) to traverse the rows. 9. The main method and command-line arguments are not included in the subset. In free-response questions, students are not expected to invoke programs. 10. Students are required to understand when the use of static methods is appropriate. 11. If a subclass constructor does not explicitly invoke a superclass constructor, the Java compiler automatically inserts a call to the noargument constructor of the superclass. 12. Students are expected to implement constructors that initialize all instance variables. 13. Students are expected to write interfaces or class declarations when given a general description of the interface or class. See Quick-Reference Below Chapter 5, Lesson 4 Though not required, the course covers both console input (Chapter 6) and GUI/Swing (Chapters 12, 13) main() is covered in Chapter 2, Lesson 2 Chapter 11, Lesson 3 Chapter 15, Lesson 6 Chapter 11, Lesson 1 Chapters 10, 11, 15, 16, 26 Page 8 of 10

9 14. Students are expected to extend classes and implement interfaces. Students are also expected to have knowledge of inheritance that includes understanding the concepts of method overriding and polymorphism. Students are expected to implement their own subclasses. Students are expected to read the definition of an abstract class and understand that the abstract methods need to be implemented in a subclass. Students are similarly expected to read the definition of an interface and understand that the abstract methods need to be implemented in an implementing class. 15. Students are expected to understand that conversion from a subclass reference to a superclass reference is legal and does not require a cast. 16. The use of this is restricted to passing the implicit parameter in its entirety to another method (e.g., obj.method (this)) and to descriptions such as the implicit parameter this". 17. The use of generic collection classes and interfaces is in the AP Java subset, but students need not implement generic classes or methods. 18. Students are expected to know a subset of the constants and methods of the listed Standard Java Library classes and interface Chapters 11, 15, 16, 26 Chapter 15, Lesson 3 See Java Quick Reference table below Java Quick Reference class java.lang.object...boolean equals(object other)...string tostring() class java.lang.integer...integer(int value)...int intvalue()...integer.min_value...integer.max_value class java.lang.double...double(double value) Chapter 15, Lesson 5 Chapter 15, Lesson 5 Chapter 15, Lesson 5 Page 9 of 10
