Hi all,

I made a little Magic 8Ball program which runs okay - it asks for input, then displays a random result from an array of responses (like the real thing, basically). I'm now trying to expand it so it keeps taking input and prints responses until the user types "q". To do this I'm using a While which checks if the input String is not equal to q, so:

!String1.equals(String2)

But this throws an error saying blabla can't be resolved (blabla is the input from the scanner):



Spot the newbie error and help a poor lost soul.

You need to declare the variable outside the loop, and initialize it. Something like :

Thanks, that got the job done!

Here's the code so far; it works, but it probably needs some cleaning.



The prompt asks you to type a question. q prints "have a nice day" in Dutch (when I first tried the do... while, typing q printed a random prediction before quitting, so I added an if...else to replace it with something more proper).

EDIT: sorry, broke the formatting there.
 
It is sorta covered in the JavaRanch Style Guide.
