Java and Object Orientation: An Introduction

An introduction to the field for both students and those actively involved in the software industry. Object orientation is discussed before going on to introduce Java, and object oriented concepts are illustrated throughout using Java, backed by examples for readers to follow. Design is included as well as coding, and guidance is given on how to build OO applications in Java. The construction of applications, not just applets is discussed in detail, showing how to turn any application into an applet. Java style guidelines are included, meeting the latest release of Java.
