Core Java 6 Programming Fundamentals Training

Core Java 6 Programming Fundamentals is a three-day, fast-paced, quick start to Java 6 training course geared for developers who have prior working knowledge of object-oriented programming languages such as C++. Throughout the course students learn the best practices for writing great object-oriented programs in Java 6 using sound development techniques, new improved features for better performance, and new capabilities for addressing rapid application development. In addition to the normal exercises that are liberally sprinkled throughout the course, there is a case study that covers the entire spectrum from use cases to object-oriented design to implemented classes. This case study supplements the course and can be used during and after the course as a reference and a tool for reviewing and practicing what was learned in class.

Students who attend Core Java 6 Programming Fundamentals will leave this course armed with the required skills to develop solid object-oriented applications written in Java, using sound coding techniques and best coding practices.

At the conclusion of the course, attendees will be able to:

• Understand not only the fundamentals of the Java language, but also its importance, uses, strengths and weaknesses
• Understand the basics of the Java language and how it relates to OO programming and the Object Model
• Work with the Java Virtual Machine and understand what functions it performs in running Java applications
• Learn to use Java multi-threading and exception handling features
• Understand and use classes, inheritance and polymorphism
• Work with various simple and complex data constructs as well as fields and methods
• Understand and use collections and generics including new Java 6 features and capabilities
• Take advantage of the Java tooling that is available with the programming environment being used in the class

Throughout the three-day course, students will be led through a series of progressively advanced topics, where each topic consists of lecture, group discussion, comprehensive hands-on lab exercises, and lab review.
