How can instantiate FaceRecognizer in opencv-2.4.9?

edit

I'm working with java in netbeans and library opencv-2. What I want to do is to instantiate the class FaceRecognizer algorithm LBPH but not how. I tried doing this. FaceRecognizer fac = new FaceRecognizer();     and nothing happens, it gives me error I tried this way. FaceRecognizer createLBPHFaceRecognizer fac = (); and does not work, gives me error. I want to use the method train and predict method for recognizing faces, but not how to start. Excuse my English.
