chemistry

I don't know about you people but I love me some Gnuplot. Properly used, that software produces beautiful images, charming in their simplicity and clarity, that I am very fond of. For no particular reason, one day I caught myself thinking how good would it be if I could create pictures of such cartoonish charm and vibrant clarity to go into my papers and personal scientific journal. So went head first into a batshit project to code a gnuplot-based molecule visualizer. So far it is tailor made for my specific type of molecule. Basically covalently bonded atoms that form ligands, which

I have to write a program that takes a user's chemical equation as an input, like 12 CO2 + 6 H2O -> 2 C6H12O6 + 12 O2, and watch if the amount of Atoms is on both sites the same. Is there any way to calculate and parse this easily? For example: 12 CO2 + 6 H2O -> 2 C6H12O6 + 12 O2 12*2+6*2 -> 2*6+2*12+2*6+12*2 In this case there should be the Output "false". This is my code but it's actually is only to try out something: public static void main(String[] args) { Scanner s = new Scanner(System.in); List<String> list = new ArrayList<String>(); String input = ""; while (!(input.equals("end"))) {
