I need to read image in java.
Then I should to convert it to 565RGB
In addition it would be good to resize this image to 320 x 240.
How should I do it? Help me please.

I know such information:
1)It is possible to read image by its URL.

ImageIcon imgThisImg = new ImageIcon(imageURL);

2) It is possible to create image instances that supports 565RGB.

BufferedImage bufImg = new BufferedImage(320, 240, BufferedImage.TYPE_USHORT_565_RGB);

3)BufferedImage inherits ImageIcon , so it is possible to perform such operation

Image imgPicture ...
BufferedImage  bufImg = (BufferedImage) imgPicture;

But I haven’t any idea, will bufImg in this case have BufferedImage.TYPE_USHORT_565_RGB format?
How to stretch, to squeeze or to cut this picture to get size 320 x 240?

    The most convenient method to read image from any source (File,Stream,URL) is

    BufferedImage bufImg = ImageIO.read( imageURL );
