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.
hi I have problem passing elements from a stack to paint method. the problem is am poping elements from 2 stacks in main method and passing them to paint method and considering the elements from 1st stack as x coordinate and elements from 2nd stack as y coordinate and need to draw a ellipse on the window using these elements. my prob is while pasing them from main method to paint method the values are changing as null and am unable to pass them to paint method inspite of declaring them as global. can anyone help me in solving this.
Since Java has no global variables, and the standard "paint()" method takes no user-supplied parameters, I'm afraid you're going to have to give us more to go one. Perhaps a bit of code showing where you "pass" the variables, and another bit where they're "received", and a third bit where they're declared.
