This table lists the errata we've found (or been told about) so far. They are listed in reverse chronological order, so it's easy to see whether there are any new entries since you last looked.

If you are the first to report a new one we'll thank you in the Remarks.

We should probably provide this same list sorted by page number to make it easier for you to see whether an error you've found is already in the list. If the list gets long we will do that. We hope it's never necessary.

 Access for this field should be private, which is not the default.

 Belongs in Chapter 7, not in Chapter 6.
 To solve this problem you must deal with an Exception.

 The asterisk means the solutions to these exercises appear later in JOI source code. Byt they don't.

 if (sh.getDot().isRoot())

}
 Our convention calls for braces in an if or else statement even when the body is just one line.

 private final static String os = "Juno";

private final static String OS= "Juno";
private final static String VERSION = ...
 Our convention wants UPPERCASE identifiers for final static fields. These changes force corresponding changes later in Juno.java. Thanks to Abrar Chaudhry.

 Our convention requires a new line for the opening brace of a method body.

 Our convention says that the opening brace for the body of a declaration  should be on its own line.

Missing parenthesis. Never type code into a document - always paste from a program that compiles and runs! Thanks to Abrar Chaudhry

Prompt missing a space after the colon. Cosmetic fix.

 This method has no parameters, so @param is a javadoc error.

 Standard four line header comment missing.
Added header lines with file name, copyright, authors.

 3/shapes/Box.java
(and some other source files)
 Problem: Internet Explorer  thinks file is a web page, not Java source.
Fix: pad initial lines with blanks so that any HTML in javadoc comments starts after 256 characters have been read.
 When MSIE sees a file type it does not recognize it looks at the first 256 characters to try to guess what to do. If it finds any HTML markup it decides the file is a web page. But sometimes javadoc contains HTML markup, which confuses Explorer. Thanks (again) to Dimpi S. Chheda.
