LinkedHashSet size() method in Java

The Java.util.LinkedHashSet.size() method is used to get the size of the LinkedHashSet or the number of elements present in the LinkedHashSet.

Syntax:

Linked_Hash_Set.size()

Parameters: This method does not takes any parameter.

Return Value: The method returns the size or the number of elements present in the LinkedHashSet.

Below program illustrate the Java.util.LinkedHashSet.size() method:

// Java code to illustrate LinkedHashSet.size() method
import java.util.*;
import java.util.LinkedHashSet;

public class LinkedHashSetDemo {
    public static void main(String args[])
    {
        // Creating an empty LinkedHashSet
        LinkedHashSet<String> set = new LinkedHashSet<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 LinkedHashSet
        System.out.println("LinkedHashSet: " + set);

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

Output:

LinkedHashSet: [Welcome, To, Geeks, 4]
The size of the set is: 4
