Head First Java 
by Kathy Sierra, Bert Bates

Following are the changes made in the 8/03 reprint.



[9]  code example in right hand column;
int x = 4; // assign 3 to x
now reads
int x = 4; // assign 4 to x

x = x + 1; // or we'd loop forever
now reads:
x = x - 1; // or we'd loop forever


{11}  "Sharpen your Pencil";
The command specified under "Given the output:" :

% java Test
now reads
% java DooBee



(15)  2nd sentence under item #1 -
"Declaraing" 
now reads: 
Declaring


[23]  code at top of right-hand column (exercise A);
The comments state that the code would run forever without a line added to the
program, however the line added in the answer would not prevent infinite looping:

class Exercise1b {
	public static void main(String[] args) {
		int x=1;
		while (x<10) {
			x=x-1;          //THIS IS THE ADDED LINE
			if (x>3) {
				System.out.println("big x");
			}
		}
	}
}

The added line now reads
	x = x + 1;



(32)  Last paragraph;
First sentence reads:
"So objects have instance and variables and methods,..."
now reads:
"So objects have instance variables and methods,..."



{41}  Code Magnets code snippets;
In the two following code snippets "System.out.print" now reads "System.out.println"

void playTopHat() {
	System.out.print("ding ding da-ding");
}

void playSnare() {
	System.out.print("bang bang da-bang");
}

additionally, to create the specified output "bang bang da-bang" now reads "bang bang ba-bang"

The code is given correctly in the exercise solutions on page 44.



(51)  Last paragraph;
The last sentence of the last paragraph is cut off.  It reads:

"Don't worry, by the end of the book you'll have most of"

The continuation now reads:

"these memorized".


(58)  Text against number (2);
Text reads:
  Create a new int array with a length of 7
now reads:
  Create a new Dog array with a length of 7


(61)  left column;
in class BooksTestDrive, the next to last statement is

System.out.println(myBooks[x].Author);
now reads:
System.out.println(myBooks[x].author);


(66)  right column;
in class BooksTestDrive, the next to last statement is

System.out.println(myBooks[x].Author);
now reads:
System.out.println(myBooks[x].author);



(72)  4th paragraph;
Currently - 
If a method takes an parameter ...
now reads - 
If a method takes a parameter ...


{157}  8th code magnet;
Current:
  for (int z = 0; z < a.size(); z++) {

now reads:
  for (int z = 0; z < al.size(); z++) {



{157}  Sixth code block;
"public class ArrayList6 {"

now reads:

"class ArrayList6 {"

to be consistent with the solution on page 159.

Alternatively,

"class ArrayList6 {"

on page 159 now reads:

"public class ArrayList6 {"

to be consistent with the Code Magnets exercise on page 157.


(212) paragraph on the right
varaiable,
now reads
variable,


(249)  Footnote within the sidebar box (i.e. very last sentence);
The footnote states:
   "... (you'll see that on page 22)."
now reads:
   "... (you'll see that on page 252)."


(250)  Second paragraph, first sentence;
"Look at the Stack series on page 17 again,"
now reads
"Look at the Stack series on page 248 again"


(299)  3rd paragraph ("The JavaSound API");
"Musical Insrument Digital Interface" 
now reads
"Musical Instrument Digital Interface"


(307)  metacognitive tip;
4 lines from bottom of first paragraph:  
you're 
now reads 
you've



{328}  First paragraph, class definition;
"public class MiniMusicCmdLine"

now reads:

"public class MiniMiniMusicCmdLine"

to match the instantiation of the object two lines down.

Alternatively,

"MiniMiniMusicCmdLine mini = new MiniMiniMusicCmdLine();"

now reads:

"MiniMusicCmdLine mini = new MiniMusicCmdLine();"

to match the class definition (MiniMusicCmdLine).



[342]  Program SimpleGui1B method "go";
There is a line missing from the method:

Method reads:
public void go() {
  JFrame frame = new JFrame();
  button = new JButton("click me");
  button.addActionListener(this);
  frame.getContentPane().add(button);
  frame.setSize(300, 300);
  frame.setVisible(true);
}

Now reads:
public void go() {
  JFrame frame = new JFrame();
  button = new JButton("click me");
  button.addActionListener(this);
  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); // Missing
  frame.getContentPane().add(button);
  frame.setSize(300, 300);
  frame.setVisible(true);
}




(345)  First bullet, second line;
"Add buttons, menus, radion buttons, etc."

"radion" now reads "radio"


(352)  'Sharpen your pencil' section at the bottom of the page;
It says:
Given the pictures on page 17 ...
it now reads:
Given the pictures on page 351 ...



[356]  the third class on the page (LabelButtonListener),  line3;
it says:
label.setLabel("That Hurt!");
It now reads:
label.setText("That Hurt!");



(427)  2nd paragraph last sentence;
"FileInputStream" 
now reads:
"FileOutputStream"



{437}  top of the page in the NextCardListener class;
the last line of the classes' method uses a deprecated method on the JButton nextButton :

nextButton.disable() 
now reads 
nextButton.setEnabled(false);
