Day 2: A Taste of Object-Oriented Programming
NOTES AND CORRECTIONS
- Line 15 of Listing 2.2 is incorrectly formatted over two lines. If
you're having trouble creating a version of the program that will compile,
replace Line 15 with the following correctly formatted source code:
- System.out.println("This is a " + sex + " " + color +
- On Page 47, the description of the Jabberwock application's main()
method contains a typo. The Jabberwock object is created in line 23
of the program, not line 2.
SOURCE FILES
- Q: There's a difference between yesterday's HelloDan class and
today's Jabberwock class that I don't understand. In the public static
void main() statements for these programs, why does one have
String[] arguments within the parenthesis, and the other has String
arguments[]? -- J.S.
- A: We're getting ahead a bit, but the difference is because
arrays can be created in two ways -- by putting the brackets next to the
class or data type, as in String[] arguments, or putting them next
to the variable name, as in String arguments[]. It's a matter of
personal preference which to use, though I was striving to use the
String[] arguments style consistently in this book (in other words,
oops). This subject is covered in full during Day 5,
"Lists, Logic and Loops."
