Write a Java Program to Access elements from a LinkedList.

import java.util.LinkedList;

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

// add elements in the LinkedList
languages.add(“Python”);
languages.add(“Java”);
languages.add(“JavaScript”);
System.out.println(“LinkedList: ” + languages);

// get the element from the LinkedList
String str = languages.get(1);
System.out.print(“Element at index 1: ” + str);
}
}

2: Using iterator() method

import java.util.LinkedList;
import java.util.Iterator;

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

// Add elements in LinkedList
animals.add(“Dog”);
animals.add(“Horse”);
animals.add(“Cat”);

// Creating an object of Iterator
Iterator<String> iterate = animals.iterator();
System.out.print(“LinkedList: “);

while(iterate.hasNext()) {
System.out.print(iterate.next());
System.out.print(“, “);
}
}
}

3: Using listIterator() method

import java.util.LinkedList;
import java.util.ListIterator;

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

// Add elements in LinkedList
animals.add(“Dog”);
animals.add(“Horse”);
animals.add(“Cat”);

// Create an object of ListIterator
ListIterator<String> listIterate = animals.listIterator();
System.out.print(“LinkedList: “);

while(listIterate.hasNext()) {
System.out.print(listIterate.next());
System.out.print(“, “);
}

// Iterate backward
System.out.print(“\nReverse LinkedList: “);

while(listIterate.hasPrevious()) {
System.out.print(listIterate.previous());
System.out.print(“, “);
}
}
}
