Answer 1

If you read in the image as a BufferedImage , you can use the getType() method.

Answer 2

There is post here that is trying to read a 8-bit and 24-bit bmp file. http://www.javaworld.com/javaworld/javatips/jw-javatip43.html?page=2

Here it tries to get the number of bits like this:

int nbitcount = (((int)bi[15]&0xff)<<8) | (int)bi[14]&0xff

Once you get this count you can validate this what type of image it is based on this bit count.
