Course Overview

“Java continues to be the leading language in the world of development.”

 

Java brings an Object-Oriented approach to programming, which allows even the newest Java developers to start modelling the world around them in code, and to start coding like a developer.

This course provides an overview of the software development process in addition to introducing important programming constructs and methodologies. As this is an introductory course, no pre-requisite qualifications are necessary, but any experience in Computing and particularly in Programming is advantageous.

This course is designed to meet the needs of candidates who are currently working in related fields and want to up-skill or for those who wish to pursue entry-level roles in the ICT sector. This course is also ideal for those who wish to pursue further study in Computer Science.

Why Study Java Programming?

  • Java Developers average salaries in Ireland range from around €40,000 to €70,000
  • Skilled Java Developers are very much in demand in Ireland
  • Rapid career progression is available based on performance

Java is the most commonly used programming language in the world.
According to the computer software company, Oracle, 3 billion devices run on Java. It is a solid core language that you will find in web and non-web environments, all operating systems and in all types of devices and it is a great precursor to learning other programming languages.

A good understanding of Java will prepare you for many open, well-paying developer jobs.
