Duration: 5 days

Print Outline in PDF format

Course Description

This course introduces the Java programming language and how to develop Java applications using IBM’s Rational Application Developer (RAD). Students will learn the syntax of the Java programming language, object-oriented programming using Java, exception handling, file input/output (I/O). The students will also be exposed to dynamic programming in java which includes Sockets, HTTP Processing, RMI, Servlets, Java Beans and Java Server Pages.

During the course, students will develop and test Java applications using RAD as an IDE along with Websphere Application Server (WAS).

Topics

• Basic Java
• Introduction to RAD IDE
• Branching and looping
• Objects  and Classes

• Introduction to Websphere Application Server
• Introduction to JDBC
• Introduction to Java Beans
• Introduction to Java Servlets
• Basic introduction to Java Server Pages
• Overview of Enterprise Java Beans

Practical work

This course covers extensive practical exercises; these exercises take students through all major aspects of the design and development of Java programs. The Students will also be introduced to various wizards and tools available from IBM RAD.

What you will learn

After completing this course, the student should be able to:

• Immediately be ready 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
• Apply dynamic java programming using Sockets, HTTP Processing and RMI
• Create Java Beans, Servlets and Java Server Pages in conjunction with JDBC
• User WAS as an Application Server

Audience

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

Prerequisites
