Description:

Gentle Java and OO Development is geared to audiences with no background in Object-Oriented programming or Java. It uses a steady pace and numerous hands-on labs to provide an easy entry into the world of Java and OO Programming. J

Java is one of the most important programming languages used today, and its correct usage is a critical part of many systems being written now. The basics of the language are relatively easy, but the challenge lies in learning how to use it well. This is especially true regarding the Object-Oriented nature of Java, which for many developers is a new way of approaching system design and construction.

This course covers the core OO and Java concepts that developers need to use the Java programming language to create well designed Java programs. It focuses on key OO capabilities and how to use them in Java. This includes material on creating well designed Java classes, using encapsulation, building more complex functionality with composition, and using inheritance to share functionality and create specialized types.

This course is suitable for environments using Java 1.4, Java 5, or Java 6. The material includes coverage of all the new Java capabilities, such as Generic Collection classes, and clearly points out which capabilities are supported in which environment. All labs are doable in any of the supported Java environments.

This course draws on our extensive experience to provide a solid understanding of the concepts and practices needed to write good object oriented programs in Java. Be prepared to work hard and learn a great deal! This course can be followed by our Intermediate Java course. The course can be held on-site & customized to fit your needs.
