java中怎樣把圖片存放在代碼中

有時候不想把圖片資源放在目錄里，讓用戶看到，我用的方法是將圖片的像素矩陣存在代碼里。可能比較笨，具體做法是：

MediaTracker mt = new MediaTracker(aFrame); //媒體跟蹤器

Image img = Toolkit.getDefaultToolkit().createImage("畫刷.jpg"); //得到圖片

mt.addImage(img, 1);

try {

      mt.waitForAll();

   }

catch (InterruptedException ex) {

   }

BufferedImage bi = new BufferedImage(16, 16, BufferedImage.TYPE_INT_RGB);

bi.getGraphics().drawImage(img, 0, 0, 16, 16, f);

int[] rbg = new int[bi.getWidth() * bi.getHeight()];

bi.getRGB(0, 0, 16, 16, rbg, 0, 16); //利用BufferedImage得到像素矩陣

for (int i = 0; i < rbg.length; i++) {

      System.out.print(rbg[i] + ","); //打印

   }

再在代碼中創建靜態對象

private static int[] penPixels = {

      16777215, 16777215, 16777215, 16777215, 16777215, 16777215, 16777215,

 };//打印出來的矩陣

private static MemoryImageSource misPen = new MemoryImageSource(16, 16,

      penPixels, 0, 16);

public static Image imgPen = Toolkit.getDefaultToolkit().createImage(misPen);

這樣就可以直接使用imgPen圖片了。
