## Some Old News

- March 9, 2022 — Lab assignments for my Fall 2021 Introductory Programming class are available on the course web page at https://math.hws.edu/eck/cs124. The course covered Chapters 1 through 7 in Version 8.1.3 of this textbook. That page also has links to solutions for most of the labs.
- September 24, 2021 — OpenJDK 17 is now available and can be downloaded from https://adoptium.net. This textbook has recommended getting OpenJDK from adoptopenjdk.net, but AdoptOpenJDK has transitioned to Adoptium, and you should look for new downloads at adoptium.net.
- August 1, 2021 — Version 8.1.3 is released, with updates to information about Java versions and about Eclipse in Section 2.6. There are some other small changes, including a few error corrections.
- May 7, 2021 — The lab assignments from my Spring 2021 Introductory Programming course, using Chapters 1 through 7 of this book, can be found at http://math.hws.edu/eck/cs124/index_s21.html.
- December 29, 2020 — Version 8.1.2 is released. This small update fixes a few errors, adds very short introductions to two new Java features (text blocks and records), and updates the information about programming environments in Section 2.6.
- May 19, 2020 — Version 8.1.1 is released. This is a really tiny update, released for the web and PDF versions of the book only. The main motivation was a change in the links to the print versions at lulu.com. I also updated Section 2.6 to reflect the fact that the current version of Java is Java 14, and Subsection 3.6.5 to say that the new `switch` statement syntax is now an official part of the language.
- July 2, 2019 — Version 8.1 is released. This is a minor update whose main purpose is to make it clearer how to use the book with Java 11 and JavaFX. The major changes are in Section 2.6. A few short topics from Java 11 and Java 12 have also been added. The main web address for the book, http://math.hws.edu/javanotes, now points to the eighth edition.
- May 15, 2019 — The lab assignments from my Spring 2019 Intermediate Programming course, using Chapters 8 through 13 of the eighth edition, can be found at http://math.hws.edu/eck/cs225/.
- December 5, 2018 — The official release of the Eighth Edition. Once again, I am indebted to John Ganci, who contributed many corrections to the "beta" version of this edition.
