Description

  • Type

    Course

  • Location

    Edinburgh (Scotland)

  • Duration

    5 Days

The aim of this Course is to give experienced C++ students a fully rounded general knowledge of client / server programming with Java providing not just basic skills but moving onto more advanced topics including Collections, Threads, I/O, Servlets and JavaServer Pages. During the Course the student will write many applications, classes, servlets and JSPs ensuring that the statements taught are. Suitable for: This course covers all major aspects of client / server programming with Java. It is essentially a condensed version of courses EC21 (Java Primer), EC22 (Java Programming) and EC31 (Java Servlet Programming) and is aimed at highly competent programmers who have detailed knowledge of similar programming techniques using C++.

Course Objectives
The aim of this Course is to give experienced C++ students a fully rounded general knowledge of client / server programming with Java providing not just basic skills but moving onto more advanced topics including Collections, Threads, I/O, Servlets and JavaServer Pages. During the Course the student will write many applications, classes, servlets and JSPs ensuring that the statements taught are fully understood and practical experience is gained. On completion of this Course the student will be able to:

  • understand the fundamental language differences between C++ and Java
  • Take advantage of and understand Interfaces
  • Use the Collections Framework (both Java 1.1 and Java 1.2 implementations)
  • Create and handle Exceptions
  • 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
  • Write Servlets that interact with HTTP clients
  • Understanding servlet multi-threading issues / pitfalls, session tracking and JavaBean manipulation.
  • Write Applications/Servlets that manipulate records in a Database using JDBC
  • Code effective JavaServer Pages using Model, View, Controller design pattern methodologies.

Course Format: 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 simple but complete application. 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.
