3,847 PointssubSet method not found and missing in Oracle documentation
Although the subSet method works in Craig's treehouse workspace, my workspace and command line code do not recognize it, even after importing relevant classes. I looked through Java SE 7, 8, 9, and 10 documentation and cannot seem to find subSet. It would make sense for subSet to be the counterpart to subList, so does anyone know how he got it to function?
