  • About Java

    Java is a programming language originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to bytecode (class file) that can run on any Java Virtual Machine (JVM) regardless of computer architecture

    Java is general-purpose, concurrent, class-based, and object-oriented, and is specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere". Java is considered by many as one of the most influential programming languages of the 20th century, and widely used from application software to web application.

Design Patterns in Java Software

Course Outline

This course seeks to develop, for the experienced Java programmer, a strong, shared vocabulary of design patterns and best practices. The course begins with a discussion of how to recognize and apply design patterns - that is, how to incorporate pattern awareness into one's own analysis, design, and implementation practices. The main body of the course focuses on the Gang of Four design patterns, with a chapter each on creational, behavioral, and structural patterns. Classroom time is about evenly split between discussion, group design exercises, and coding labs to reinforce finer points of important patterns.

This is not a patterns catalog: it is as much a study of how to "think in patterns" as it is an introduction to several of the most important patterns. Students will be challenged to bring their own previous development experience to the discussion, to see the patterns in everyday design and coding solutions. The course puts more emphasis on some patterns than others. We believe that students will be better served by going into a few patterns in depth, with lively discussions of several others, than by following a regular routine of discussion and examples over every GoF pattern.

  • Start to think in terms of design patterns.
  • Recognize and apply patterns to specific software development problems.
  • Use known patterns as a shared vocabulary in designing and discussing solutions.
  • Use Factories and Singletons to control object creation, for a variety of reasons.
  • Use Observers, Observables, and Model/View/Controller systems to decouple application behavior and preserve code scalability.
  • Understand the full motivation for the Command pattern and take advantage of Command frameworks in JFC.
  • Implement Adapters, rather than building redundant classes or creating intermediate data structures for consumption by existing code.
  • Understand and apply a range of other J2SE and J2EE patterns to improve code quality and scalability, and to produce high-quality solutions right off the bat.
  • Solid Java programming experience is essential - especially object-oriented use of the language. Language features and techniques that are integral to some lab exercises include interfaces and abstract classes, threading, generics and collections, and recursive methods.
  • Previous experience with UML (Unified Modeling Language) will be helpful, but is not critical. The course uses UML class diagrams extensively but keeps notation fairly simple, and also includes a quick-reference appendix.
