Write a Java program to retrieve an element (at a specified index) from a given array list.

Pictorial Presentation:

Sample Solution:-

Java Code:

import java.util.*;
  public class Exercise4 {
  public static void main(String[] args) {
  // Creae a list and add some colors to the list
  List<String> list_Strings = new ArrayList<String>();
  list_Strings.add("Red");
  list_Strings.add("Green");
  list_Strings.add("Orange");
  list_Strings.add("White");
  list_Strings.add("Black");
  // Print the list
  System.out.println(list_Strings);
  // Retrive the first and third element
  String element = list_Strings.get(0);
  System.out.println("First element: "+element);
  element = list_Strings.get(2);
  System.out.println("Third element: "+element);
 }
}

Sample Output:

[Red, Green, Orange, White, Black]                                     
First element: Red                                                     
Third element: Orange
