eclipse - Filling a HUD in Java -

i've decided on making hud picture above, don't know command in java need use can fill top half , bottom half separately.

know how use g.fillrect(); command, , take around twenty of these commands fill said half.

public class hud {      private player player;     private bufferedimage image;     private font font;     private font font2;     private  int phealth = player.gethealth();      public hud(player p) {         player = p;         try {             image = imageio.read(getclass().getresourceasstream("/hud/hud_test.gif"));             font = new font("arial", font.plain, 10);             font2 = new font("sans_serif", font.bold, 10);         }         catch(exception e) {             e.printstacktrace();         }     }      public void draw(graphics2d g) {          g.drawimage(image, 0,  10,  null);         g.setfont(font2);         g.setcolor(color.black);         g.drawstring("health:", 30, 22);         g.drawstring("mana:", 25, 47);         g.setfont(font);         g.drawstring(player.gethealth() + "/" + player.getmaxhealth(), 64, 22);         g.drawstring(player.getcubes() / 100 + "/" + player.getmaxcubes() / 100, 55, 47);         g.setcolor(color.red);         g.fillrect(1, 25, phealth * 25, 4);         g.setcolor(color.blue);         g.fillrect(1, 31, player.getcubes() / 33, 4);     } } 

this code hud far.
in filling shape help.

removed idea #1! (it didn't seem work.)


okay, idea #2:

image1

image2


image3

so, there 3 .png images.

• draw image1 first, followed drawing image2 , image3 directly on top of it.
• to fill either red/blue bars, clip image2 , image3 accordingly (i.e. cut away left sides)

take @ this on clipping.
require minor calculations on how clip, based on hp/mana of player, should enough.

should (clipping , overlaying done in paint)

update (problem solved, using idea #2!):

code:
