Arraying a series of colors

Question

hi all, i'm facing a problem working on a matching game and wonder if anybody could point me in the right direction.
see, i have a 9x10 gridboard with 90 pieces to match, and there're 45 pairs of pieces of the same Oval look, except with different colors. i am implementing 9 different colors, so that each piece will have 5 pairs to match up when the player plays the game, meaning a total of 10 pieces for each different color. the thing is, i'm not sure if there is any way to array my colors (the basic ones, like white, red, magenta, cyan etc.) so that I can run a loop to allow the computer to place each piece behind a grid on the board.
so far, my coding looks like:
final int SETS = 10;
final int COLORS = 9;
for(int draw = 0; draw < SETS; draw++)
     for(int max = 0; max < COLORS; max++)
          int x = (int) (java.lang.Math.random()*GRIDCOLS);
          int y = (int) (java.lang.Math.random()*GRIDROWS);
          if(position[x][y] == EMPTY)
               g.setColor(Color.white);
               shape(x,y); //calls the shape to be drawn
               position[x][y] = FILLED;
          else if(position[x][y] != EMPTY)
               max--;
the part in question lies in that bolded sentence. i do not know how to change colors for that part so that the loop creates one piece of each different color, before looping that 10 times.
can anybody help me a little?

Answer 1

There is a Color c'tor, which uses a single int value. If you write the colors as hex its similar to the way you specify colors in html or drawing applications.
The format is 0xRRGGBB (red, green, blue).
Eg 0xFF0000 = red, 0xCCCCCC=some light gray etc.
You can easily put those numbers into one array and use those numbers for constructing the color object.
int []col={0xFF0000,0x00FF00,0x0000FF};
g.setColor(new Color(col[x]));Easy, ne? :)
