Java hashmap with arrayList as values videos
I saw a video couple of days ago but don't remember where ,The speaker constructs a hashmap where he stores the course name as key and grades as values in the video and then he iterates and goes constructing complex data structures using hashmap anyone knows where this or similar video is available because most videos on hashmap i see is simple with keys as strings and another simple data types as values
