Get Tail Set from TreeSet in Java
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<String> set = new TreeSet<String>();
set.add("78");
set.add("56");
set.add("88");
set.add("54");
set.add("76");
set.add("34");
Now, get the Tail Set −
SortedSet sorted = set.tailSet("56");
The following is an example to get Tail Set from TreeSet −
Example
import java.util.*;
public class Demo {
public static void main(String args[]){
TreeSet<String> set = new TreeSet<String>();
set.add("78");
set.add("56");
set.add("88");
set.add("54");
set.add("76");
set.add("34");
System.out.println("TreeSet elements...");
Iterator<String> i = set.iterator();
while(i.hasNext()){
System.out.println(i.next());
}
SortedSet sorted = set.tailSet("56");
System.out.println("TailSet = " + sorted);
}
}
Output
TreeSet elements... 34 54 56 76 78 88 TailSet = [56, 76, 78, 88]
