Write a Java Program to Add elements to a LinkedList

PROGRAM: Java Program to Add elements to a LinkedList

/*Java Program to Add elements to a LinkedList*/

Add Elements Using add()

import java.util.LinkedList;

class Main {
public static void main(String[] args){

// create a linkedlist
LinkedList<String> languages = new LinkedList<>();

// Add elements to LinkedList
languages.add(“Java”);
languages.add(“Python”);
languages.add(“JavaScript”);
System.out.println(“LinkedList: ” + languages);
}
}

2: Add element at the specified position

import java.util.LinkedList;

class Main {
public static void main(String[] args){

// create a linkedlist
LinkedList<String> languages = new LinkedList<>();

// add elements to LinkedList
languages.add(“Swift”);
languages.add(“Python”);
System.out.println(“LinkedList: ” + languages);

// add element at the specified position
languages.add(0, “Java”);
System.out.println(“Updated LinkedList: ” + languages);
}
}

3: All all elements from other collection to LinkedList

import java.util.LinkedList;

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

mammals.add(“Dog”);
mammals.add(“Cat”);
mammals.add(“Horse”);
System.out.println(“Mammals: ” + mammals);

LinkedList<String> animals = new LinkedList<>();
animals.add(“Crocodile”);

// Add all elements of mammals in animals
animals.addAll(mammals);
System.out.println(“Animals: ” + animals);
}
}
