This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
I'm quite new to Java FX and now I'm trying to build the game mastermind. I've tried multiple ways to create the game but the start doesn't even work. I have the layout of the game. I have six colors to choose. When I press one color all the four circles change color while only one should change.
I hope someone can put me in the right direction.
