To get the Tail Set from TreeSet, use the tailSet() method. Tail Set begins from a point and returns the elements greater than the element set in the beginning.First, create a TreeSet and add elements −TreeSet set = new TreeSet(); set.add("78"); set.add("56"); set.add("88"); set.add("54"); set.add("76"); set.add("34");Now, get the Tail Set ...
