Out of curiosity, why can you say
int b;
or
char c;
but you must give a boolean a value?
Finally done with blackjack!!!! I will have no more questions
with which to bug you all... until the next project.
Have a great day,
Alex

Initialize the boolean to something, for example: false.
Take care,

Subject: another java question
Hi all,
Sorry, but I have just one more question about this blackjack
program. For
some extra credit I can include a function that adds 11 to a hand
with an
ace when the total of the hand is below
11 and adds 1 with an ace when the total is more than 11. I have
this
function inside a method called getHandTotal(). I use a boolean
called ace
and set it to true if the adding loop encounters an ace so that,
after the
loop, I can use an if statement whose condition is that the
handTotal was
greater than
11 and ace==true. Inside this I subtract 10 from the hand (same
as
subtracting the 11 that was added in the loop and then adding the
one I
want). The problem is that the compiler says that ace might not
have been
initialized, but just after starting the method I say boolean
ace; Is it
because I am setting ace to true inside a loop or something? I
have no idea
why it won't work. All times I call ace it is lower case. I
have tried
just saying if (total>11 && ace and if (total>11 && ace==true but
both
result in that same error. Thanks for any help.
Have a great day,
Alex
