### How to Tell which Printing You Have

On the copyright page (facing the first page of the Preface), there is a printing history of the book. The printing history is a row of numbers that—at the 1st printing—looks like this:

10 9 8 7 6 5 4 3 2 1

At each subsequent printing, one number is removed from the end of this row of numbers to indicate which printing of the book you have. For example, the last number in the row of numbers in the 2nd printing is 2, and so on.

[B3C2] = fixed in Big Java's 3rd printing, Java Concepts 2nd printing
[B3] = fixed in Big Java's 3rd printing

In Exercise P2.13, move 2π from the numerator to the denominator three times: f=1/(2pi sqrt(L C)), f_min=1/(2pi sqrt(L C_max)), f_max=1/(2pi sqrt(L C_min))

In Self Check 9, change
double result = (x + y) / (y - x);
to
int result = (x + y) / (y - x);

Section 5.9
In the program fragment at the very end, change
for (int j = 0; j < i; j++)
to
for (int j = 0; j <= i; j++)

Change While (i < size / 2) to While i < size / 2

In Figure 15, the first array should have type double[][].

String line = nextLine(); should be String line = in.nextLine();

pre while (!Character.isWhiteSpace(line.charAt(j)))  should be
while (Character.isWhiteSpace(line.charAt(j)))

In Syntax 9.2, change choices = new ArrayList<String>; to choices = new ArrayList<String>();

“with the first queen in position a2” should be “with the first queen in position b1

Change the last equation from T(n) = 1 + log2(n) to T(n) = T(1) + log2(n)
Page 700
Change “Write a loop that prints every second element of a linked list of strings called words.” to “Write a loop that prints every other element of a linked list of strings called words, starting with the element at the front.”

In the last row of the “Unprocessed Input” column in the last table, change 4 + 5 to 4 × 5

Change TreeSet<K, V> to TreeSet<E>

Instead, we make ... outer class → Instead, we make Node an inner class inside the LinkedList class. The methods of the outer class can access the public features of the inner class. (We could even declare the inner class as private, so that it cannot be accessed anywhere other than from the outer class. However, for simplicity we do not do that in this book.)

Remove static from the getNode method.

“Figure 17” should be “Figure 16”

Change log(n + 1) to log2(n + 1) (2x)
Page 824 section_7/HeapSorter.java
Change the comment “Sorts an array, using selection sort.” to “Sorts an array, using heap sort.”
Page 826
Change Self Check 16 to: “What is the result of calling HeapSorter.fixHeap(a, 1, 4) and then HeapSorter.fixHeap(a, 0, 4) where a contains 1 4 9 5 3?”

In the last figure, the "X" node should not be the right child node of node n2 but should be the right child node of n4.
Page 845 Self Check 13
Change “If you have an array list
ArrayList<String> a = new ArrayList<>(10);
how do you fill it with ten "*"?” to: “If you have an ArrayList<String> a, how do you replace all elements with "*"?”
Page 851
Change Self Check 22 to: “Suppose we want to implement a method that computes both the minimum and maximum of an array of measurable objects, returning an array of length 2:
public static <E extends Measurable> E[] minmax(E[] objects)

Why doesn’t this work?” Change the answer to: The method would need to create the array of length 2 and type E. However, you cannot construct an array of a generic type.

assertEquals(letters, t.toString().remove(" ", ""));

Change “435,974,400 red-black trees with black height 2” to “25,728,160,000 red-black trees with black height 3”
Chapter 17 Worked Example 2 Page 18
Change “The resulting tree has constant black height, but it might still not be a valid red-black tree because it might have double-red violations. We could test just that, but we need to have a general method that tests the red-black properties after the removal.” to “The resulting tree might not be a valid red-black tree. It might have some leaves with greater black height than the node to be removed, or it might have double-red violations. We will develop a method to check that a red-black tree is valid and call it before and after the removal.”
