JDK Source Code (Activity)

Overview

Title	JDK Source Code (Activity)
Overview	In literature, we study some "great works" in that language. For example, in English we might read works by Jane Austen, Charles Dickens, and William Shakespeare. In computing, we should also study some "great works", such as operating systems, programming languages, and compilers. This set of activities explores parts of the source code for the Java Development Kit (JDK), including selected parts of Math.java, Arrays.java, ArrayList.java, and String.java. These files are only a small part of the complete JDK.
Prerequisites	Read, written, and debugged Java programs with: javadoc comments; variables & expressions; classes with fields, methods, and constructors. String uses arrays. ArrayList uses generic type parameters.
Learning Objectives	After successfully completing this activity, the learner should be able to: Describe common items in file and class comments. Describe common patterns in API classes, including: overloaded methods, wrapper methods, high comment-to-code ratio (Arrays) Describe, trace, and use common Arrays methods, including: sort(), binarySearch(), equals(), fill() (ArrayList) Describe, trace, and use common ArrayList methods. (String) Describe, trace, and use common String methods. (String) Describe the Unicode standard and its general structure. (String) Describe how Java compares strings lexicographically.

Notes for Instructors

Assessment

• How will the activity be graded?
• How will learning will be measured? Ideally, there should be a way to measure each of the objectives described above.
• How will feedback to the student be determined?

These are classroom POGIL activities, so all teams should complete it in class with correct answers. Thus, these activities are typically not graded, but there might be related quiz or exam questions later.
