question44 from java cap

[Anshuman Acharya]

44. Which statements are true about GridBagLayout ?
A) Weight x and weight y should be 0.0 and 1.0
B) If fill is both, anchor does not make sense.
C) It divides its territory in to an array of cells.
D) While constructing GridBagLayout , you won't tell how many rows and columns the
underlying grid has.
the answer is abc. i'm pretty sure a is wrong and my question is NOT regarding that...
my question is why not d? where do we declare the # of rows and columns?

[Priya Kannan]

Hi,
You are infact right.The option d IS correct.That's what the Javacap exam also says though it has a mistyped 'C' in place for 'D'.
The wrong choice is
"It divides its territory into an array of cells."
This statement cannot be right for GridBagLayout since it can span multiple rows & coloumns.
By the way why do you say choice 'A' is false???

Hi,
I think the A is false.
when I learn java by using "Core Java", I remeber the value is from 0 to 100.(some other books are 0 to 10)
In RHE page 318 " weight can be any numbers"(line 7 from bottom)

How cone choice 2 is correct?. Is there any funda? behind it

[Kevin Hou]

the answer B is correct.
for example: you place a button in cell, when the button is smaller than the cell, you can use anchor field to place the button in nine positions.
on the other hand, if you use the fill BOTH, the button is as big as the cell. so the anchor doesn't make sense any more.
