Simple Problem of programming
Well, I'm a student of Java. And I'm having problems with a coding... well... The thing is that I have to switch the values I gave to 2 "tables" (sorry, I don't know these terms in English xD), I mean, there are columns and rows... I will write my code here to a better understanding...
/**

I hope someone can help me doing this ^^ it gets me a headache .-. I hope this is the right forum xD, I get confused with all those subforums.>
