this set of code producing stack overflow error due infinite recursion (at least, think is). have been staring @ code long time , can't figure out error happens be. if can point out why getting such error, great. public void drawvalues(graphics g, graphics2d g2, int x, int y, int a, int b){ if (b>8){ b = 0; a++; x = 61; y+=66; } if (a==8 && b==8){ g.drawstring(string.valueof(solver.rows[a][b]), x, y); } else{ g.drawstring(string.valueof(solver.rows[a][b]), x, y); drawvalues(g,g2, x+66, y, a, b++); } } it state rows 9x9 2d array, , b start @ 0 this because using post-increment(b++) instead of pre-increment(++b) when make recursive calling of drawvalues method. if use post-increment, argument increment after method has been invoked. hence, in case, variable b never changed. so, should use pre-increment: ... drawvalu...
