in the context of procedural programmingin the small." Since this frame of reference is essentially uselesswhen attacking large-scale problems, students must later "re-learnhow to approach problems. Instructors can present material from apoint of view that will "make sense" throughout the curriculum.Presentation and justification of programming principles and goodtechniques is easier.* Emphasis on the distinction between class specification andimplementation. Students learn to develop coherent classspecifications early on, and to build components that conform tocarefully defined, consistent specifications. The result is moremain-tainable, error-free code.* Early emphasis on testing and test-driven implementation.Students develop a habit of testing as part of the implementationprocess. Testing is essential to ensure quality programs.* Current presentation of object-oriented design and Java. Studentsbenefit from seeing general approaches to commonly occurring designpatterns in a specific, well-defined context. This will also makeit easier for students to "get the point" when such topics areintroduced in upper-level design and software engineering courses.Other features include an emphasis on event-driven interfaces,rather than traditional procedural I/O; informal use of standardUML notation* Optional interactive exercises are designed for use with theopen-source DrJava integrated development environment (IDE) - apopular tool for compiling and testing programs
