Getting an Element : ArrayList « Collections « Java Tutorial

The ArrayList class supports retrieval of a single element by index with 'public Object get(int index)'.

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

public class MainClass {
  public static void main(String args[]) throws Exception {

    List list = new ArrayList();
