方法二:By Converting HashSet to TreeSet
import java.util.*;
public class HashSortOfSort {
public static void main(String[] args) {
Set<String> set = new HashSet<>();
set.add("geeks");
set.add("practice");
set.add("contribute");
set.add("ide");
System.out.println(set);
List<String> list1 = new ArrayList<>(set);
Collections.sort(list1);
System.out.println(list1);
SortedSet<String> sortedSet = new TreeSet<>(set);
System.out.println(sortedSet);
}
}
[practice, geeks, contribute, ide]
[contribute, geeks, ide, practice]
[contribute, geeks, ide, practice]
