This course covers all major aspects of programming with Java using a choice of IDE (Integrated Development Environment).
It is aimed at programmers who are already able to code simple Java applications and wish to broaden their knowledge with a greater understanding of the Java API.
Covers all versions of Java up to and including Java SE 7.
An understanding of programming with Java or C++ is required. Students must be able to code simple Applications and Classes.
Knowledge of this can be gained by attending our Java Primer course EC21.
The aim of this course is to give students a fully rounded general knowledge of programming with Java.
Whereas the Java Primer (EC21) course provides basic skills, this course moves onto more advanced topics including Collections, Generics, Threads, I/O, and Networking.
During the course the student will write many classes ensuring that the statements taught are fully understood and practical experience is gained.
The course is taught using a choice of IDE (Integrated Development Environment). The skills needed to use this software are presented as part of the course.
On completion of this course the student will be able to:
- Take advantage of and understand Interfaces
- Use the Collections Framework
- Understand which type of collection to use for a specific purpose
- Sort Objects using Comparable and Comparator interfaces
- Create and handle Exceptions
- Code custom Exception classes
- Use the Java Input/Output classes
- Understand and use Serialization to achieve persistence
- Understand multi-threading and synchronization and use the various techniques available to create separate threads
- Create socket based applications using the Networking classes
Development will be performed using:
- Websphere Studio Application Developer
- Rational Application Developer
- the Java Development Kit (JDK) plus a text editor
For on-site courses (i.e. at your premises), we are more than happy to tailor the course agenda to suit your exact requirements. In many cases, we are able to build your in-house standards and naming conventions into the delivered course.

Practical sessions make up a large part of the course, allowing delegates to demonstrate and reinforce the lectures given. During these sessions the delegate will build a complete application, gaining in complexity throughout.
Examples are used extensively, ranging from simple code snippets to full applications with complete 'real world' functionality. These are supplied at the start of the course and it is encouraged that the delegates execute and 'experiment' with these under the instructor's guidance as they are introduced.
These examples are available to take away, along with the delegate's own work.
The comprehensive Student Guide supplied is fully indexed serving as a useful reference tool long after the course has finished. Delegates will also be able to access a free help-line with technical questions relating to topics covered on the course.
