New, just learning java...

[Criki]

Hi all, just to make sure everyone knows, I'm as new as new can be to Java. I'm a VB programmer trying desperately to explore other languages.

I was given a small project to learn on by debugging. I've got a few simple things out of the way, like case sensitive stuff and all, but now I'm lost.

for (int i = 0 ; i < 3; i++);
     for (int j = 0; j < 3; j++)
          for (int j = 0; j < 3; j++)
 	return "";

The red line shows an error when compiling. Cannot resolve symbol. Variable i.

Well, all the lines before it use the variable i and there doesn't seem to be a problem.

I know it's probably something ridiculously simple, but not knowing the language makes the easiest problems impossible.

Thank you!!

The thing is you are declaring and using the variables i and j in the for loop. It's OK in Java, but the problem with the red line is it uses the variable j once again. It declares it twice.

Get rid of the red line completely, and the code will work.

If you know C/C++, Java is very similar to these languages in terms of syntax.

Ha, not only do I not know java, I can't proof read either!

Sorry!! I guess I should have re-read what I copied in there. The red line should be...

if (square[i][j].setText() == ' ')

Sorry!
