Hello,

Please take a look at the online documentation for menu or macro  
driven thresholding...

http://rsb.info.nih.gov/ij/docs/menus/image.html#adjust

or if you want to really use Java then you'll need to dive into  
ImageJ's source code - see ...

ImageProcessor.setThreshold() in http://rsb.info.nih.gov/ij/developer/ 
api/index.html

Cheers,
Ben
