Intermediate Java 7 Using Rational™ Application Developer (RAD)

Course ID: INTMJ

Intermediate Java 7 and OO Development is a fast paced course suitable for programmers with some previous experience in working with Java and Object-Oriented (OO) programming (equivalent to taking our Gentle Java course). It 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 goes well beyond the basics of Java and OO programming and covers important topics such as composition, inheritance, polymorphism, interfaces and exceptions, which are all key to creating well-structured OO systems using Java. After coverage of these important areas, it moves on to more advanced topics such as JDBC and JPA 2 (for database access), the Java Collections Framework - including the important generics capabilities, Java I/O, assertions, inner classes, and the reflection API. Finally it covers useful tools for day-to-day programming such as ant, maven, 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.

This course is geared toward Java 7, but can be used in almost any recent Java environment. The course is hands-on, fast-paced and interesting. Be prepared to work hard and learn a great deal! The course can be customized to fit your needs.

All labs are done using the RAD Development Environment, and the lab instructions include detailed directions on using RAD and the RAD wizards and tools.
