Java loop structure

iDunno

Hello, i need help on a loop stucture for a java programming i am doing.
Imagine that you have a 20x20 grid and i need to get "fishes" to appear clockwise starting at the top left corner, then going in circles, in a swirl pattern, clockwise.

01 02 03 04 05 06 07 08 09 10
38 39 40 41 42 43 44 45 46 11
37 ****************47 12
36*****************48 13
35*****************49 14
34*****************50 15
33*****************51 16
32********************17
31 *******************18
30********************19
29 28 27 26 25 24 23 22 21 20

and so on
if i could get a basic loop stucture, taht would be good
thanks

I cannot think of an easy way to do this. can you give a little more background about the project, or is this a specific problem posed for the class?

Also, how is it indexed?

0,0...n,0
.

.
0,m...n,m

i assume?

iDunno

yes, it is indexed starting at 0,0 in the upper left and 19,19 at the bottom

iDunno

woohoo, i figured it out
thanks anyways!

I'd like to see it, for my own curiosity

       {
               int a = 0;
               int b = 0;
               int c = 1;
               int color = 1;
               int z = 0;
               FishGfx f = new FishGfx(g,20,20,1000);
               while (z< 10)
               {
               for (a=0+z,b=0+z;b< 20-z;b++,c++)
               f.drawFish(g,a,b,color,String.valueOf(c));
               color++;
               if (color ==10)
               	color = 1;
               for (a=0+z+1,b=19-z;a<20-z;a++,c++)
               f.drawFish(g,a,b,color,String.valueOf(c));
               color++;
               if (color ==10)
               	color = 1;
               for (a=19-z,b=19-z-1;b>= 0+z;b--,c++)
               f.drawFish(g,a,b,color,String.valueOf(c));
               color++;
               if (color ==10)
               	color = 1;
               for (a=19-z-1,b=0+z;a> 0+z;a--,c++)
               f.drawFish(g,a,b,color,String.valueOf(c));
               color++;
               if (color ==10)
               	color = 1;
               z++;
               }
               z=0;

attached are all the files if you want to execute it and see the output
