In C++ we can claim tracker with : Ptr<tracker> tracker = TrackerKCF::create(); I have install contrib module. But I don't know how to claim tracker in Java. And I can't find any sample.

indeed, there are no java samples, but something like this should get you started:

import org.opencv.tracking.*;

Tracker tracker = TrackerKCF.create();

// then:
Rect2d roi = new Rect2d(11,12,100,100);
tracker.init(image, roi);

// later:
boolean ok = tracker.update(image, roi);
// if it returns false (object lost), you have to create a new Tracker, with a new ROI
