Introduction to Java Using Rational Application Developer v7.0 Training

Course#: WA1587
Courseware: Available for sale

This course introduces the Java programming language and how to develop Java applications using RAD v7.0. Students learn the syntax of the Java programming language, object-oriented programming using Java, exception handling, generics, collections, and file input/output (I/O). During the course, students will develop and test Java applications using RAD v7.0.

Throughout the course students will also work on a "project" which develops a complex Java application by applying principles learned to meet changing application requirements. This project is intended to simulate the programming environment they would encounter in real-world projects by providing application requirements and challenging the student to write Java code to meet those requirements.
 
Topics
 
  • Java basics
  • Java basics
  • Basic introduction to WebSphere Studio Application Developer
  • Branching and looping
  • Objects
  • Advanced class concepts
  • Arrays
  • Exceptions
  • Collections and Generics
  • Stream I/O
Practical work
  Extensive practical exercises take students through all major aspects of the design and development of Java programs. Students will be introduced to various wizards and tools available from RAD.
What you will learn
  After completing this course, the student should be able to:
  • Apply OOP principles
  • Design OO applications using abstraction, encapsulation, modularity and hierarchy
  • Use Java exceptions to guarantee graceful error recovery for your application
  • Create and use inner classes in your program to make them concise and clear
  • Do input/output using Java
  • Create servlets and JavaServer Pages
  • Use RAD for Java application development
Audience
 

This course is intended for programmers who are interested in adding Java to their skills.

This course focuses only on the basics of Java Programming and provides lots of hands-on experience writing Java code as the foundation for future Java training. This course assumes that if students require a detailed introduction to Java Enterprise technologies they will take another course on Java Enterprise. If students require an introduction to Java Enterprise but will not be taking another course on Java Enterprise the following course may be more appropriate. The following course provides an introduction to Java Enterprise but does not contain the "project" featured in this course.

WA1556 - Introduction to Java and Java Enterprise Using Rational Application Developer v7
