Java




// Java code to illustrate
// SortedSet.remove() method
 
import java.util.*;
 
public class SortedSetDemo {
    public static void main(String args[])
    {
 
        // Creating an empty Set
        SortedSet<String> set
            = new TreeSet<String>();
 
        // Use add() method to
        // add elements into the Set
        set.add("Welcome");
        set.add("To");
        set.add("Geeks");
        set.add("4");
        set.add("Geeks");
 
        // Displaying the Set
        System.out.println("SortedSet: "
                           + set);
 
        // Removing elements
        // using remove() method
        set.remove("Geeks");
        set.remove("4");
        set.remove("Welcome");
 
        // Displaying the Set after removal
        System.out.println(
            "SortedSet after "
            + "removing elements: "
            + set);
    }
}
Output: 
SortedSet: [4, Geeks, To, Welcome]
SortedSet after removing elements: [To]
