COURSE OVERVIEW

This course introduces the Java programming language and how to develop Java applications using RAD 8.0. Students learn the syntax of the Java programming language, object-oriented programming using Java, exception handling, generics, collections, and file input/output (I/O). During the course, students will develop and test Java applications using RAD 8.0. This course also covers a basic introduction to Java EE (Java Enterprise) since that is a common reason that people are learning about Java.

Throughout the course students will also work on a "project" which develops a complex Java application by applying principles learned to meet changing application requirements. This project is intended to simulate the programming environment they would encounter in real-world projects by providing application requirements and challenging the student to write Java code to meet those requirements.

AUDIENCE AND PREREQUISITES

This course is intended for programmers who are interested in adding Java to their skills.
The students should be familiar with object-oriented principles and the concept of object-oriented programming.
