Question:
Do we only need to write comments only for
describing the class and methods? Or we have to wirite
comments explaining what we do each line in the mothod
body as well?
Do we have to express the comments using"/**/"or we
can use "//"too?
Answer:
Comments for the class and methods should be enough.
If you do something obscure within a method an additional
comment explaining your logic should
be included.
Class and method comments should use the /* */ format.
Single line comments in the body of a method often use the //
format.

Question:
Are we allowed to declare JFrames as instance varialbes in the class other than the DayNameWindow
class and the QuarteringWindow class?
Answer:
Check the description of the assignment again.
In quartering window it says to use instance variables for
the additional
JFrames.
In DayNameWindow you are not creating a new window you are
just changing
the title of the existing window.

Question:
I have a question about the OverlappingWindow class. In the first method
[setOverlap(int dH,int dV)] I have no problem setting the
amount of overlap,
but then when it comes to the [overlap()] method how do I
show it (or create
it) without using the dH and dV variables? Or how can I
get to those
variables?
Answer:The variables are in your instance of OverlappingWindow
class. Having set
them in the setOverlap method use them in the overlap method.

Question:
The assignment advises us to play around with the Date and Day class
before we go on but I have no idea how to use the Day class. Any extra
advice?
Answer:Create an instance of each and call the different methods
available to see
how they work. Try using the return value from one class's methods as an
argument for the other class.

Question:
Should we actually create four new JFrames each time the
method quarter() is called, or could we just change the size and
location of our existing JFrames that we access through instance
variables?
Answer:
You may simply recycle the same JFrames, with new sizes and
locations, each time you call quarter(), quarterVertical(), or
quarterHorizontal()

Question:
Since we don't use the Date variable in DayNameWindow (except
to set it), why do we need it?
Answer:
You may need to use a Date object to generate the integer
representing the current day of the week. This is something you need
when you create a Day object.

Question:
Should our overlapping window be the same size as the current
window?
Answer:
Yes.

Question:
Does the method setOverlap() display the overlapping
window?
Answer:
Not according to the specification: the method
overlap()
does.

Question: Can you clarify the methods in the QuarteringWindow?
Answer:The methods of
QuarteringWindow create
*and display* four new JFrames. Each of the three methods creates
and displays the new JFrames in a different pattern.

Question: For the DayNameWindow class, it asks me
to display the current day on the title of the JFrame.
so, let say today is jan.22, wednesday,
how should my title looks like?
my display now is like this: "22wednesday"
Answer:
No it shouldn't look like the above. The class Day has a method today()
that returns
the day of the week as a String,
displayToday() sets the title to "Wednesday". As was suggested in the
assignment handout. Before starting the DayNameWindow class spend some
time experimenting with both the Date and Day classes.

Answer:
There is an easier way to include Day.class.
Once you download Day.class for assignment 1, you'll need
to let DrJava know where to find it. The simplest way to do this
is to store Day.class in the directory or folder where you're
working on assignment 1, and then create and compile at least
one class in that directory. Once you've done that,
Day.class will be known to DrJava, and you'll be able to
include statements such as:
Day d;
... in your code.
January 21:
Question: How do I make Day.class known to DrJava?
Answer:
To make classes in the current folder available to the drjava
interactions pane (and to classes that you write), you need to go
under "Edit" in DrJava, then "Preferences", then "Resources". Once
there, you add the directory you're working in to the Extra Classpath
box, and save this.

Question: When I shrink a ResizingWindow why is the minimum width
always 112?
Answer:
There's a constraint in MicroSoft Windows that limits the size of a
JFrame. As it says in the assignment description we will test your
submissions with reasonable data.
