SortedSet size() method in Java with Examples

Last Updated : 30 Sep, 2019

The size() method of SortedSet interface is used to get the size of the SortedSet or the number of elements present in the SortedSet. Syntax:

int size()

Parameters: This method does not takes any parameter. Return Value: The method returns the size or the number of elements present in the SortedSet. Note: The size() method in SortedSet is inherited from the Set interface in Java. Below program illustrate the java.util.Set.size() method:

Java

// Java code to illustrate Set.size() method

import java.util.*;

public class SetDemo {
    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("Set: " + set);

        // Displaying the size of the Set
        System.out.println(
            "The size of the SortedSet is: "
            + set.size());
    }
}

Output:

Set: [4, Geeks, To, Welcome]
The size of the SortedSet is: 4
