java arraylist get object at index code example

Example 1: ArrayList indexOf(Object o) method in java

import java.util.ArrayList;
public class ArrayListIndexOfMethodExample
{
   public static void main(String[] args)
   {
      ArrayList<Integer> al = new ArrayList<Integer>(5);
      al.add(8);
      al.add(6);
      al.add(5);
      al.add(7);
      al.add(9);
      System.out.print("ArrayList values are: ");
      for(Integer num : al)
      {
         System.out.print(num);
         System.out.print(" ");
      }
      // indexOf() method to find index of 5
      int position = al.indexOf(5);
      System.out.println("\nElement 5 is at index: " + position);
   }
}

Example 2: java arraylist access index

List<String> cities = new ArrayList<String>();
cities.add("Tuguegarao City");
cities.add("Tabuk City");
cities.add("Davao City");

System.out.println(cities.get(1)); //prints "Tabuk City"

Example 3: how to select a element in an arraylist java

{
    public static void main(String[] args) 
    {
        ArrayList<String> list = new ArrayList<>(Arrays.asList("alex", "brian", "charles", "dough"));
         
        String firstName = list.get(0);         //alex
        String secondName = list.get(1);        //brian
         
        System.out.println(firstName);
        System.out.println(secondName);
    }
}
