    Default free memory of bufferedimage

    hi all,

    i have the following code.

    BufferedImage img=new BufferedImage(29342,450,BufferedImage.TYPE_INT_RGB );

    Graphics2D g2d=img.createGraphics();
    g2d.drawImage(r.getAsBufferedImage(), 0, 0, null);
    g2d.finalize();
    g2d.dispose();

    img.flush();
    img=null;

    but i cannot free img object all uts memory since i know there is the reference to it, but for this problem how to solve it? thanks.

    You should not directly call finalize...this is for the garbage collector. The g2d.dispose() call should release all resources associated with the Graphics object you created. The garbage collector works on its own time, and it will free up the memory to unreferenced/out of scope objects when it sees fit - which may or may not be immediately
