bufferedimage - Combining PNG Images Java -

i trying loop through file of png images , stitch them form 1 image. have gotten work without using loop , combining 2 images file. assuming looping isn't working. images located in file called "images". appreciate input!

        file file = new file("images");      file [] morefile = file.listfiles();     string [] images = new string [morefile.length];      for(int =0; <images.length; i++)         {images[i] = morefile[i].getname();         }      int x = 0;     int y = 0;     bufferedimage result = new bufferedimage(             controller.getsize().width*2, controller.getsize().height, //work these out             bufferedimage.type_int_rgb);     graphics g = result.getgraphics();      for(string image : images){         system.out.println(image);          file path = new file("images");         try{imageio.read(new file(path, image));          system.out.println("it goes here");          bufferedimage bi = new bufferedimage((2*510),(2*439),bufferedimage.type_int_argb);         bi =imageio.read(new file(path, image));          g.drawimage(bi, x, y, null);         g.dispose();     /// system.out.println(dafuck);         x += bi.getwidth();          if(x > result.getwidth()){             x = 0;             y += bi.getheight();         }         }catch (exception e) {             system.out.println("is exception>?");          }     }      try {         imageio.write(result,"png",new file("results"));     } catch (ioexception e) {         // todo auto-generated catch block         e.printstacktrace();     }
