// Java programm to Demonstrate the // use of contains() in LinkedList import java.util.LinkedList;

public class Geeks { public static void main(String args[]) { LinkedList l = new LinkedList<>();

    // Use add() method to 
    // add elements in the list
    l.add("Geeks");
    l.add("for");
    l.add("Geeks");
    l.add("10");
    l.add("20");

    System.out.println("LinkedList: " + l);

    // Check if the list contains "20"
    System.out.println("\nThe List contains '20': "
                       + l.contains("20"));

    // Check if the list contains "Hello"
    System.out.println(
        "The List contains 'Hello': "
        + l.contains("Hello"));

    // Check if the list contains "Geeks"
    System.out.println(
        "The List contains 'Geeks': "
