Mismatch in number of items

[ferortega]

@vermavijay i have analyzed the MovieLens 1M dataset file and it contains 3706 items.

Here is the code to test it:

BufferedReader dataset = new BufferedReader (new FileReader (new File ("MovieLens1M.txt")));
		
Set <Integer> items = new HashSet <Integer> ();
		
String line = "";
while ((line = dataset.readLine()) != null) {
	String [] s = line.split("::");
	int item = Integer.parseInt(s[1]);
	items.add(item);
}
		
System.out.println(items.size());

dataset.close();
