- November, 2007 -- A bug has been discovered in TextIO.java by students of Prof. D. McCarthy of Brock University: When the input source is changed, unread data from the previous source remained in the buffer so that the next "get" operation would take its input from the old source instead of the new source. A related bug was found in TextIOApplet.java by Praveen Pendyala in India that affects some of the TextIO-based applets on web pages in the book: When the user presses the "Run Program" button, there could still be some data in the buffer from the previous run of the program. In addition to these bugs, I have noticed an error in Subsection 12.5.3, in which I said that the locale code for Japan is "jp"; in fact, the code for Japan is "ja". Finally, I thank Beatrice Santorini, who has reported a variety of typographical errors in the book. These bugs and errors are fixed in Version 5.0.2 of the textbook, released in November 2007.
- May 1, 2007 -- Version 5.0.1 has been released. This version is identical to Version 5.0, which was published in December 2006, except for the correction of typographical errors and a very small number of substantive errors. (For a list of errors that have been corrected in this version, see the News and Errata page for Version 5.0.)
- February 5, 2007 -- OOP2_from_Univ_KwaZulu-Natal.pdf. Anban Pillay (School of Computer Science, University of KwaZulu-Natal, Durban, South Africa) has put together a set of notes for a second course in Object Oriented Programming using Java. This is the second version of his notes; it is based on Version 5.0 of my book. The notes use parts of Chapters 4, 5, 6, 8, 9, 10, and 11 together with additional material from other sources. A nice PDF (1.4 MB) of the notes can be downloaded through this link. See the preface of the PDF for more details.
- January 16, 2007 -- I have made a printed version of the full textbook available at lulu.com. See http://www.lulu.com/content/612392. Previously, only the first seven chapters were available in a printed version. The complete version, at 700 pages, is rather thick and a little unwieldy. (Please do not feel any obligation to buy the printed version -- I do not make any money from it.)
- January 16, 2007 -- A new "linked" PDF has been added to the download section of the main page. This PDF contains internal links for navigation and external links to material on the web site that is not included in the PDF. This PDF in more suitable for reading on line, rather than printing.
- December 18, 2006 -- Version 5.0 is released. This version of the book requires Java 5.0 or higher.
