Overview
Through a combination of instructor-led discussions and hands on workshops the course will illustrate the methods and techniques for developing applications using IBM’s WebSphere Studio Application Developer v5.1. The course will offer a practical introduction to the Java programming language and discuss Java topics like; class definitions and hierarchies, polymorphism, encapsulation, abstraction, exception handling, Java data types, flow control, conditional testing, single and multidimensional arrays, JDBC access and the creation of Java applications. Each of the topics will be taught while utilizing the basic components of IBM’s toolset; project creation and navigation, source editor and team development, java compiler, debugging and testing tools and the other aspects of IBM’s WebSphere Studio Application Developer IDE
Prerequisites
Each student should have a basic understanding of the Windows environment and a fundamental knowledge of any application programming language. No object-oriented background is required.
Class Format
Lecture and Lab
Audience
Application developers, programmers and other technical professionals transitioning to Java that will be utilizing IBM’s WebSphere Studio Application Developer v5.1 as their IDE development tool
Learning Objectives
After completing this course, the student should be able to:
- Understand the roots and benefits of object
oriented application design
- Illustrate each of the key OO concepts of
inheritance, polymorphism, encapsulation and
abstraction.
- Understand a class definition and its components
of data and access methods.
- Depict the major differences between procedural
application development and object-oriented
systems in both design and implementation.
- Utilize the source repository and debugging
features of WSAD v5.1 for managing all java
source testing binary files.
- Understand the role of exception handling
and its implementation.
- Illustrate Java file access considerations
using streams and buffers.
- Depict the role of JDBC in RDBMS database
access and updating.
- Illustrate the basic concepts behind even-driven
programming and its role in an OO application
environment
