Introduction to Java 2 Programming (5 days)
Description
This courseware training guide book will focus on helping students leverage their existing skills in languages like C or C++ to learn how to develop applications in Java. The details are only for client-based applications and creating standalone applications. The class is designed as a foundation for learning Java technology and mastering the core details of the language.
Suggested PrerequisitesPrior programming experience in one of the following:
1. At least one object-oriented language such as a .NET language (e.g., C#, VB.NET), Java, C++, SmallTalk
2. Or significant programming experience in a modern language such as MS Visual Basic
