i'm doing this project in which i'll be moving my mouse using my webcam. so the code has imported some java packages. i have no experiance in java. how can i understand the code. and to write more codes like this, do i have to learn java or i can simply use MATLAB? below is my code:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

import java.awt.Robot;

import java.awt.event.*;

mouse = Robot;

vid = videoinput('winvideo', 1);

preview(vid);

for f=1:1000

    d=getsnapshot(vid);
    d = imresize(d,[480  640]);
    i=im2bw(d,.56);        
    [label num]=bwlabel(i,8);
    stats = regionprops(label,'all');
    ind= find([stats.Area] < 8000 ); 
    if (num==1)
        xx=stats(ind).Centroid(1);
        xx=(1366-(xx*2.14)); 
        xx
        yy=stats(ind).Centroid(2);
        yy=yy*1.6;   
        yy
        mouse.mouseMove(xx, yy);                             
    elseif(num>1)               
        mouse.mousePress(InputEvent.BUTTON1_MASK);
        mouse.mouseRelease(InputEvent.BUTTON1_MASK);
        mouse.mousePress(InputEvent.BUTTON1_MASK);
        mouse.mouseRelease(InputEvent.BUTTON1_MASK);
    end
    pause(.001);
end
