I downloaded the Classic Indigo, in hopes of being able to examine the source code for Java to see how various things are accomplished.

"The classic Eclipse download: the Eclipse Platform, Java Development Tools, and Plug-in Development Environment, including source and both user and programmer documentation."

Did I misread this description? Is the "source" being referred to the source for Eclipse rather than Java?

Yes, it is the Eclipse source. Oracle distributes the Java source with
the Java JDK (not with the JRE). If you install an Oracle JDK, it will
include the source.

Thank you. I was able to download the JDK version and indeed there are source files available.

What puzzles me is that they are organized very differently. Files which are present in rt.jar are not in a source file that matches rt.jar.

Thus when I press <F3> on a class like AudioSystem, I'm brought to the "AudioSystem.class" with a note that I am allowed to click an "Attach Source" button. But the source being requested is for rt as a whole, is it not?

Ah! Attaching the src.zip that is provided, at this juncture indeed exposes the source code for AudioSystem.

Thank you!
