Java Training Courses

Course Description:
Java has rapidly established itself as a language for applicatio
development and server side computing, but with a reputation as being too large and slow for real-time and embedded software development.

This course aims to show how Java running on the Linux operating system can be used in real-time and embedded projects and importantly provide developers with significant advantages over other languages. A complete tour of the Java facilities for the resource constrained environment is provided, including the J2ME Personal Profile and the Real-Time Java Specification.

Who Should Attend:
The course is suitable for anybody who wishes to gain a thorough understanding of the Java programming language and its use in resource constrained environments running the Linux operating system.

Overview:
This five day course provides a thorough grounding in the Java language, highlighting the significant benefits the language provides real-time developers in terms of portability, concurrency, productivity and reliability.

Via a mixture of demonstration and practical sessions, delegates will gain a sound appreciation of how Java applications running on the Linux operating system provide a cost effective approach to developing robust, maintainable applications.

Forty percent of the course is spent on practical work.

Course Objectives:
• To provide an understanding of the fundamentals of the Java programming language
• To introduce Concurrency and networking aspects of Java
• To provide a complete picture of the Java landscape for resource constrained environments
• To highlight how Java can be used on embedded Linux powered hardware

Delegates will learn:
• The core Java syntax and semantics
• How to use Java on embedded Linux devices
• Write concurrent and networked solutions to real problems
• Coding with J2ME and particularly with the personal profile
• About memory and performance issues associated with Java
• How to link with C and C++

Pre-requisites:
Experience of programming in a high level language.

Duration:
Five days

Course Materials:
• Delegate Handbook

• EL-504 Developing Linux Device Drivers

Course Workshop:
The course exercises are based on a case study of a remote monitoring and control system. A configuration utility is developed and a graphical user interface in Java then added. For remote access to the system, delegates implement a full concurrent Web server that provides remote access via a standard Web browser. The item of plant to be controlled is a water pump motor. This case study highlights a complete end to end system implemented in Java and highlights the advantages and disadvantages of the language.
