BlueJ book, 7th edition
07 May 2024

A new edition of the BlueJ book is on the way.

David and I have just finished the draft manuscript for the seventh edition of “Objects First”, and sent it to the publishers.

The book will now go through the usual process (editing, layout, proofreading, etc.), but it should come out later this year.

The new edition includes four brand-new chapters, including recursion, teamwork, records, a brief history of Java, and more.

We will let you know if we have firmer dates for publication.
