    arrList1.add("Vehicle 1");
    arrList1.add("Vehicle 2");
    arrList1.add("Vehicle 3");
    arrList1.add("Vehicle 4");
    // Display Array List
    System.out.println(arrList1);
    // Insert at Index
    arrList1.add(0, "Vehicle 0");

  }
}

package com.c4learn.arraylist;

import java.util.ArrayList;

public class ArrayListExamples {

public static void main(String[] args) {

// Create ArrayList

ArrayList<String> arrList1 = new ArrayList<String>();

arrList1.add("Vehicle 1");

arrList1.add("Vehicle 2");

arrList1.add("Vehicle 3");

arrList1.add("Vehicle 4");

// Display Array List

System.out.println(arrList1);

// Insert at Index
