Getting started with IDEA - IntelliJ IDEA in Action - page 14

The JavaDoc API Paths tab tells IDEA where it can find the HTML documentation
that describes the target JDK 's source code. Adding entries to the JavaDoc API
Paths tab is also optional, but doing so gives you the ability to view documenta-
tion directly from the IDE . Specify the directories or JAR files where the JDK 's doc-
umentation can be found. Alternatively, you can enter a URL that represents the
root of the API documentation stored on a web server. IDEA uses this URL to
locate the appropriate documentation if requested. For example, for JDK 1.4.2,
you can use the documentation from Sun's web site by entering the URL http://
java.sun.com/j2se/1.4.2/docs/api/index.html.

If you install a new JDK at some point after IDEA has been installed and
configured (or add the source or JavaDoc API documentation to an exist-
ing JDK ), you can always come back to this configuration window
through the Settings menu option.

TIP

Continue as follows:

Click the OK button to accept the new JDK configuration and return to
the New Project Wizard .

7

Select the new JDK you just configured, and click the Next button to
continue.

You're prompted to select either a single-module or a multi-module
project. Modules represent a discrete piece of functionality within a project
and can be reused in multiple projects. They're discussed in depth in a
chapter 4; for now, select the single-module project and click Next .

9

You're prompted to select the type of module this project is concerned
with developing. Again, we'll go into the differences in detail in chapter
4, but for now select Java Module and click Next .

10

The next dialog in the New Project Wizard prompts you for a module
name and a module content root. This is a single-module project, so the
wizard should reuse the project's name as the name of the module. This
is sufficient for the example. The module content root is the directory
where all the work on this project will be done; use the ellipsis button
and following path-selection dialog to specify a new, empty directory, or
accept the default. The module file —the file that stores all the module-
specific settings—is typically stored in the module content root folder,
but the Change Directory button at the bottom of the window allows you
