Write simple code to add new values to java list code example

Example 1: how to make java list

//Creating arraylist example 
ArrayList<String> list = new ArrayList<String>();  
 
//Adding objects in arraylist 
list.add("Mango");    
list.add("Banana");   

//Change the element (index,"new value")
list.set(1,"Dates"); 

//Return the 2nd element, because index starts from 0
System.out.println("Returning element: " + list.get(1));

Example 2: java append to list

package com.journaldev.examples;

import java.util.ArrayList;
import java.util.List;

public class ListAddExamples {

	public static void main(String[] args) {

		List<String> vowels = new ArrayList<>();

		vowels.add("A"); // [A]
		vowels.add("E"); // [A, E]
		vowels.add("U"); // [A, E, U]

		System.out.println(vowels); // [A, E, U]

		vowels.add(2, "I"); // [A, E, I, U]
		vowels.add(3, "O"); // [A, E, I, O, U]

		System.out.println(vowels); // [A, E, I, O, U]
	}
