Yes it can be done in Java with the OpenCV Library. Try this:

MatOfKeyPoint keypoints = new MatOfKeyPoint();
FeatureDetector surf = FeatureDetector.create(FeatureDetector.SURF);
surf.detect(inputMat, keypoints);

I should note that SURF is actually very slow (just saying)

In C++ we provide threshold value in the surf object constructor so how could we set the threshold value in that code? Is there any documentation for this subject ?

SURF is not included in java Package from opencv 2.4.2 version onwards
