Description

Learn the key object technology concepts together with the current trends, tools, and techniques to support developing Java applications. Learn not only the object technology concepts, but also the fundamentals of the Java language itself, to write and organize classes to create a simple, but usable application. In our hands-on labs, take a case study from paper to product. Learn to use the Unified Modeling Language (UML) to model a business' problem domain. Take the case study through the stages of analysis and design to finally implement a simple Java program based on the study.
