convert gif into jpeg

This is what I have :
java1 :
// GifEncoder - write out an image as a GIF


java2 :
// A framework for classes that encode and write out an image in
// a particular file format.

and more.... maybe is what you need

Answer:

1)JavaTM Advanced Imaging API

2)
make java image from gif file.
and then use JPEG class - http://www.afu.com/jpeg.txt

3)
 15. (Sect. 13) How can I convert between GIF and JPEG formats?

     [*] In a word: don't.
     There's hardly any overlap between the set of images that JPEG works
     well on and the set that GIF works well on. Sometimes, with enough
     care, you can get an acceptable conversion...but most of the time
     GIF<->JPEG conversion will just turn your image to mush. It's better to
     pick the right format in the first place.
     Other sites:
        o If you're determined to convert formats anyway, try the GBM
          (Generalized Bitmap Module). The package is GNU licensed, in C and
          is very good. Find it at
          http://www.interalpha.net/customer/nyangau/
          GBM does a good job converting to JPEG, and 'lossiness' is
          adjustable to 0%. It also converts to/from about 20 other formats,
          does cropping, sizing, color mapping, gamma correction,
          halftoning, everything you could want. GBM source doesn't support
          JPEG directly, but utilizes JPEG source from IJG called jpeg-6a
          and found at
          ftp://sun2.urz.uni-heidelberg.de/pub/simtel/graphics/jpegsr6a.zip
        o For more info see the JPEG FAQ at
          http://www.faqs.org/faqs/jpeg-faq/

Answer in previos comment
