int classId = (int) detections.get(i, 1)[0]; in DnnHelper.java

[LCY3898]

Dear Sir,
After studying the project code you made, I found that the app is able to identify different kind of racing cars by using "int classId = (int) detections.get(i, 1)[0];" function. However, I would like to ask how does this function works, how can I determine the type of car by using the variables i and 1 in the bracket. I am looking forward to your reply. Thank You.
