问题 I need to cancel all selections within a JTable model object. Java provides this function "clearSelection()" which does, what I need, as far as I understand. But I am confused why this function can be called on a JTable object as well as on a selection model for a JTable object: 1) mytable.clearSelection(); 2) mytable.getSelectionModel().clearSelection(); Both ways work, but I do not understand in what situation a clearSelection() of a SelectionModel (like at 2) ) would make any sense.
