The following trails cover features added after the JDK 1.0.2 release:
The rest of the tutorial,
unless otherwise noted,
reflects the 1.0.2 release
of the JDK. Much of the 1.0.2 material is still valid,
but some of it doesn't apply to programs that use 1.1 features.
When most of our readers have upgraded,
we'll update the entire tutorial to reflect 1.1.
In the meantime, we've added
notes that point out material
that is affected by 1.1.
Within the text of many lessons, you'll find
note links, which look like this: (
notes).
Note links are usually in a header and indicate
that the section gives information
that's affected by 1.1 changes.
A note link takes you to a file that contains all of the notes for
the current lesson. For example, all the JDK 1.1 notes for
the lesson Using System Resources are in
this notes file:
java/system/_1_1notes.html.
For each note link in the lesson,
the _1_1notes.html file contains
a short note like this:
The Standard I/O Streams
The System class sports three new methods
that allow you to reassign the standard I/O streams.
See 1.1 Changes: System Class.
The first line of the note
has the same name as the section that contains the note link.
Clicking it takes you to that section.
The note then summarizes the change
and gives a link to a page
where you can find detailed information
and updated examples.
We had several goals when designing this system of notes:
-
To make them unobtrusive.
-
To allow people to find the information in a way appropriate for
their current level of Java knowledge and their learning style.
If you are new to Java, you can get the information
in the context of a lesson as you are working your way
through the tutorial.
If you are already familiar with
Java, you can walk your way through all of the notes
to learn what changes were made to the JDK.
-
To easily integrate these notes into the book form of the tutorial.
-
To provide two levels of notes: a brief summary for those
already familiar with the changes and a longer description
that talks about the change in more detail and may provide
code samples, reasoning for the change, and other information.
We hope you find this structure and the information useful.
