If you try to compile and install that with
./build.sh
like we did with
HelloWorld
,
you'll get two errors:
$
cd Desktop
$
cd code/BuildAHouse
$
./build.sh
Compiling with javac...
src/buildahouse/MyHouse.java:10: cannot find symbol
symbol : variable width
location: class buildahouse.MyHouse
BuildAHouse.buildMyHouse(width, height);
^
src/buildahouse/MyHouse.java:10: cannot find symbol
symbol : variable height
location: class buildahouse.MyHouse
BuildAHouse.buildMyHouse(width, height);
^
2 errors
And that's your first mission: declare and set an
int
variable named
width
and
an
int
variable named
height
, and set them to something reasonable for a house,
perhaps no smaller than 5 blocks high and 5 blocks wide. Or maybe 10×10
if you're feeling spacious.
Delete those comment lines and replace them with your two variables for
width
and
height
. Save the file, and then go ahead and run
build.sh
again:
$
./build.sh
