excuse me can anybody help me to made a some project which help me to compile an image with output error level of the image that has been compile,,,

i am really newbie as programmer and i had no idea how to convert a java program that successfully compile a Error Level Analysis... there many syntax really made me confuse and i tried to find what syntax in java that had same function in matlab,,

this is what i had been made "So Far" after UiGetfile

 function [] = generate_ela(filename,quality)
    %if nargin > 2 | nargin < 2
     %   error('usage: generate_ela(filename,quality)');
    %end;
   % img_orig = imread(filename);
    tempfile = 'E:\img.jpg';
    imwrite(img_orig,tempfile,'jpeg','Quality',quality);
    temp = imread(tempfile);
    delete(tempfile);
    idiff = uint8(abs(double(img_orig)-double(temp))*30);
    me = max(max(max(idiff)));
    idiff = uint8(double(idiff)*255/double(me));
    %imwrite(idiff,'ela.jpg');
    figure; imshow(idiff);

if that some of syntax was wrong please warn me... thank you...
