Introduction to VisualWorks Smalltalk
Course Description
This five-day course provides a solid working knowledge of the Smalltalk language and the VisualWorks Smalltalk development environment. Participants create Smalltalk methods and classes and develop elementary Smalltalk applications, using a broad range of VisualWorks Smalltalk browsers and tools. Participants view and use the major subclasses of the Collection and Magnitude hierarchies. Participants become familiar with the built-in configuration management system and create basic VisualWorks Smalltalk visual parts. The course format is 50% lecture and 50% hands-on computer time.
Audience
Developers who need to understand the fundamentals of object-oriented programming in Smalltalk and the VisualWorks Smalltalk environment
Prerequisites
Successful completion of either the
Object-Oriented Analysis & Design Workshop or equivalent understanding of fundamental object-oriented concepts

Has created a Smalltalk compiler
for the Java Virtual Machine. This compiler allows Smalltalk to run on any
JVM. The compiler currently produces 100% Java class files fully compatible
with the Sun Java Virtual Machine specification. This allows Smalltalk and
Java code to interact seamlessly and allows Smalltalk programs to run
anywhere Java runs! Click to learn more |
