Intermediate Java™ and OO Development
Overview

This course includes a short review of basic Java concepts, and then moves on to a comprehensive coverage of more advanced topics in Java and OO programming to provide participants with a strong grounding in using Java in a sophisticated and productive manner. This course covers important topics such as composition, inheritance, polymorphism, interfaces and exceptions, which are all key to creating well-structured OO systems using Java. Then the course moves on to more advanced topics such as JDBC (for database access), the Java Collections Framework - including the generics capabilities introduced in Java 5, Java I/O, assertions, inner classes, and the reflection API. Finally it covers useful tools for day-to-day programming such as ant, JUnit and various logging frameworks. This course covers far more than an introductory course, and provides participants with a comprehensive understanding of how to use Java's advanced capabilities in a more sophisticated manner. It teaches a number of useful techniques that enhance productivity and good system design - which Java programmers may otherwise take years to absorb on their own.

Audience

Environments using Java 5 or Java 6

Prerequisites

Programmers with some previous experience in working with Java and Object-Oriented (OO) programming.
