Changes

• July 20, 2000. I have added a search feature to the main page of the text. This might make up for the fact that the text does not have a conventional index. You can also use the search feature here.
• June 2, 2000. I added the note "This is nothing fancy -- just all the Web pages captured in a single file" to the description of javanotes3.pdf, to try to make sure that people understand what this is.

Errata

Note: These errors are fixed in the on-line version of the text on math.hws.edu. As of February 18, 2001, they have also been fixed in the downloadable versions. For further corrections after that time, see the Version 3.1 errata page.

• November 21, 2000. An error in the quiz for Chapter 8:
  • In c8/quiz.html, line 76, System.out.println(pic[i][j]) should be System.out.print(pic[i][j]).
    The same correction should be made in the answers to the quiz, c8/quiz-answers.html, line 133.
    (Without this change, the answer would be incorrect, because each character would be output on a separate line.)
• October 31, 2000. More substantive errors found by readers:
  • In c2/s5.html (Section 2.5), line 255, "(x != 0) && (x/y > 1)" should be "(x != 0) && (y/x > 1)"
  • In c5/s2.html (Section 5.2), line 250, "total1 = firstDice.die1 + secondDice.die2;"
    should be "total1 = firstDice.die1 + firstDice.die2;".
    The same error occurs in the sample programs RollTwoPairs.java and RollTwoPairsConsole.java.
    (This is an example of an error where the program runs and gives
    reasonable output, but isn't actually doing what it is supposed to do.)
  • In c5/s3.html (Section 5.3), in both lines 341 and 346, the string "Your card is" should read ""Your card is the"
• October 24, 2000. A substantive error in a quiz answer:
  • In c6/quiz-answers.html, line 151, g.fillRect(30,30,30,30) should be g.fillRect(30,30,40,40)
    (This change is required for the square to be centered in the circle.)
• September 27, 2000. Another bad link:
  • In source/index.html, line 100, <a href="Card.java">Deck.java</a> should be <a href="Deck.java">Deck.java</a>
• June 15, 2000. Some bad links:
  • In source/index.html, line 473, ../c11/s6.html should be ../c11/s5.html
  • In c6/s1.html, line 379, ../c5.index.html should be ../c5/index.html
  • In c6/s4.html, line 65, href="s5" should be href="s5.html"
  • In c11/s1.html, line 662, ../s10/index.html should be ../c10/index.html
• Some Typos:
  • In c2/s1.html, line 145, java should be Java
  • In c2/s2.html, line 214, such a tab should be such as a tab
  • In c2/s3.html, line 166, Math.round should be Math.floor
  • In c2/s3.html, line 228, remove the "+" at the end of the line
  • In c2/quiz_answers.html, on lines 4, 10, and 15>, change "Chapter 1" to "Chapter 2" in page title, headline, and first paragraph
  • In c6/index.html, line 18, event-driver should be event-driven
  • In c11/s5.html, line 66, recipee should be recipe
