package com.c4learn.arraylist;

import java.util.ArrayList;

public class ArrayListExamples {

public static void main(String args[]) {

// Create ArrayList 1

ArrayList<String> arrlist1 = new ArrayList<String>(5);

// Fill Elements in ArrayList 1

arrlist1.add("A");

arrlist1.add("B");

arrlist1.add("C");

arrlist1.add("D");

arrlist1.add("E");

arrlist1.add("F");

// Print Array List

Boolean flag = arrlist1.isEmpty();

// Print Element's Position
