propID not found, please help

edit

A friendly hi @all, I am running openCV 3.4.0 on Windows in the Eclipse IDE Version Oxygen in Java. When trying to insert specific propIDs some of them cant be found. Specifically i want to get VideoCapture Information with .get() method with the id CV_CAP_PROP_FOURCC. In another post i read, that the "CV_" part at the beginning should be lost. There the propIDs were called by the dot operator of an import like cv2. This cant be found either in my system.

here's some tutorial code. Can anyone help? Thank you in advance. Greets Che
