Understanding Java: A Technical Overview

Course Objectives

 The engaging seminar includes an introduction on the core Java platform and an introduction to its three major components: Java Micro Edition (Java ME), Java Standard Edition (Java SE), and Java Enterprise Edition (JEE / Java EE). It goes on to a broader coverage of JEE and its key components, which have become a driving force in the adoption of Java industry-wide. The workshop will also explore and analyze the challenges that organizations face as they adopt these new technologies.

Working within in an engaging learning environment, guided by our expert team, attendees will discuss and explore:

• Java’s history
• Java’s characteristics as a programming language
• The strengths and weaknesses of Java, and how it compares to other languages
• The three main Java platforms: Java Micro Edition (Java ME), Java Standard Edition (Java SE), and Java Enterprise Edition (Java EE)
• Some of the challenges in transitioning to and using Java, JEE, and Object-Oriented programming
• The business advantages and disadvantages of using Java and JEE
• The major tools, frameworks, and platforms available for Java and JEE

Course Prerequisites
