How to sort TreeSet in descending order in Java?
Given a TreeSet in Java, task is to sort elements of TreeSet in Descending Order (descreasing order).
Input : Set: [2, 3, 5, 7, 10, 20] Output : Set: [20, 10, 7, 5, 3, 2] Input : Set: [computer, for, geeks, hello] Output : Set: [hello, geeks, for, computer]
To make a TreeSet Element in decreasing order, simple use descendingSet() method which is used to change the order of TreeSet in reverse order
Below is the implementation of the above approach:
Without descendingSet(): [2, 3, 5, 7, 10, 20] With descendingSet(): [20, 10, 7, 5, 3, 2]
