graphics2d - (Java) How can I use Anti Aliasing on java.awt.geom.Area objects? -


i want apply anti aliasing on little idlegame.

on first try used g.fillrect create rectangles anti aliasing didn't work. commented things out , startet using area. still seem not apply anti aliasing. side effect got slower due use of areas.

enter image description here

private void render() {     boardparameters mbp = myboardparameters;      bufferstrategy bs = mydisplay.getcanvas().getbufferstrategy();     if (bs == null)     {         mydisplay.getcanvas().createbufferstrategy(2);         return;     }     graphics2d g2 = (graphics2d)bs.getdrawgraphics();     //clear screen     g2.clearrect(0, 0, mbp.getwindowwidth(), mbp.getwindowheight());     //draw here!      area area[] = {new area(),new area(),new area()};      drawunits(g2,area);       int[][] cs = myboardparameters.getcolorscheme();     g2.setcolor(new color(cs[0][0],cs[0][1],cs[0][2]));     g2.fill(area[0]);     g2.setcolor(new color(cs[1][0],cs[1][1],cs[1][2]));     g2.fill(area[1]);     g2.setcolor(new color(cs[2][0],cs[2][1],cs[2][2]));     g2.fill(area[2]);      g2.setrenderinghint(renderinghints.key_antialiasing,             renderinghints.value_antialias_on);      //end drawing!     bs.show();     g2.dispose(); }  private void drawunits(graphics g, area[] area) {     boardparameters mbp = myboardparameters;      (int = 0; < mbp.getrows(); i++)     {         (int j = 0; j < mbp.getcollumns(); j++)         {             animal actanimal = myboarddata.animals[j][i];             int actualarea = 0;             if (actanimal != null)             {                 int[][] cs = myboardparameters.getcolorscheme();                 switch (actanimal.getclass().getsimplename())                 {                     case "fish":                         //g.setcolor(new color(cs[0][0],cs[0][1],cs[0][2]));                         actualarea = 1;                         break;                     case "shark":                         //g.setcolor(new color(cs[1][0],cs[1][1],cs[1][2]));                         actualarea = 2;                         break;                     case "plankton":                         //g.setcolor(new color(cs[2][0],cs[2][1],cs[2][2]));                         actualarea = 3;                         break;                     default:                         system.out.println("unknown unit found in 'myboardparameters.units[" + j + "][" + + "]': " + actanimal);                         break;                 }             }else{                 //g.setcolor(color.cyan);             }             //g.fillrect(j * mbp.getcellwidth(), * mbp.getcellheight(), mbp.getcellwidth(), mbp.getcellheight());             shape shape = new rectangle2d.double(j * mbp.getcellwidth(), * mbp.getcellheight(), mbp.getcellwidth(), mbp.getcellheight());             area areaadd = new area(shape);             switch (actualarea)             {                 case 1:                     area[0].add(areaadd);                     break;                 case 2:                     area[1].add(areaadd);                     break;                 case 3:                     area[2].add(areaadd);                     break;             }         }     } }

does 1 have idea, try?

(maybe smoothing better description?)
