last paragraph

...assumes that if the hour of the day on a 24-hour clock is lower than 6 p.m., it is night
-->This should be "lower than 6:00, it is night"

Donut chart legends

For clarity and consistency with the threshold tables, the highest categories in the donut chart legends should read:
-Figure 2-2 (Java p.26/C# p.27) should be "61 or more" instead of "61+". The orange category in the second/third charts of this figure should read "31-60" instead of "30-60".
-Figure 3-2 (Java p.40/C# p.42 ) should be "26 or more" instead of "25+"
-Figure 5-1 (Java p.64/C# p.66) should be "7 or more" instead of "7+"
-Figure 6-1 (Java p.76/C# p.80) should be "51 or more" instead of "51+"

Code snippet

Note that since the code snippet on page 12 is an example of a bad practice, it also includes a SQL injection flaw. This is not elaborated upon because the focus of the exercise is to assess the code's maintainability.

Third donut chart in Figure 1-1

The third donut chart in Figure 1-1 should be the same as the third donut chart on page 26 (Java edition)/page 27 (C# edition), thus with the caption: "unit size quality profile cut-offs for a 4-star system". The cut-offs are thus (from low risk to high risk):
57%
21%
15%
7%

code snippet

Note that on p.37 (§3.2) we purposely leave the +else+ line in the code snippet to improve code analyzability (that is, removing the +else+ line would not change the code's behavior). The effect of this added line should be marginal to the actual code maintainability. Also, for the sake of consistency we apply the same coding style as in the code snippet before refactoring.

Figure 7.1

The right title: the loosely coupled components -> highly coupled components: hard to test.

Note from the Author or Editor:
P.79, figure 7.1
The right title is erroneously the same as the left one.

It should read: Highly coupled components: hard to change in isolation.

2nd paragraph

Eight out of 10 of them are are derived

'are' repeated twice

Note from the Author or Editor:
Page x, second paragraph, last sentence
Original: "Eight out of 10 of them are are derived.."
should be
"Eight out of 10 of them are derived..."

Second code snippet

No need for the line
Point position = r.getPosition();

since position is not used in the unit.

Note from the Author or Editor:
P.57, second, refactored code snippet: the following line:

Point position = r.getPosition();

is superfluous since the position variable is not used in the unit.

2nd paragraph

So far our unit contains only four lines of code
should be
So far our unit contains only six lines of code

as ending brackets count as well, too.

Note from the Author or Editor:
p.16, second paragraph:
Original: "So far our unit contains only four lines of code"
should be
"So far our unit contains only six lines of code"

Note: Since closing brackets count as well.
