Java Programming Fundamentals


This intensly practical course covers all major aspects of programming with Java. It is essentially a condensed version of the courses 'Java SE Primer Workshop' and and' Java SE Programming Workshop', but excludes topics on Threads and Networking. The course is suitable for all versions of Java up to and including Java SE 8.
Development will be performed using Eclipse, IntelliJ, NetBeans, Websphere Studio Application Developer, Rational Application Developer, Jbuilder and the Java Development Kit (JDK) plus a text editor.
For exclusive one-company, on-site presentations of this course, we can 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 as well.

Objectives

On successful completion of this course you will be able to:

  • use the major concepts of a modern, block-structured, high-level language, such as control flow, method calls and modular programming
  • structure programs using classes and other essential object-oriented features
  • take advantage of and understand Interfaces
  • use the Collections Framework
  • create and handle Exceptions
  • use the Java Input/Output classes
  • understand and use Serialization to achieve persistence.

Who Should Attend

Software developers and applications programmer coming new to the Jave programming environment.

Prerequisites

Attendees should be familiar with the Windows host environment. Knowledge of any programming language is advantageous, but is not essential.
