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
