Overview

This course introduces you to the Java programming language and the Java environment. The course begins with a brief history of Java. You will see the features that make Java unique among programming languages and learn the terms that are unique to the Java environment. The course then gives a detailed description of the Java Development Kit (SDK). It describes how to download Sun's SDK and shows how to use several of the tools that the kit provides. You will see how to compile a Java program, execute a class, and create a jar file.

Next, the course describes IBM i's support for Java. You will see the various ways to create a Java source file in an IBM i directory. The course then describes how to start Qshell, the alternative IBM i command interpreter designed to accept and process Java commands. It also covers two IBM i Java extensions. You will learn how to use CL commands that work with Java programs. You will also learn about the IBM Toolbox for Java, a collection of classes to assist you in writing Java programs that access IBM i resources.
