how to make java list

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

class scratch{
    public static void main(String[] args) {
        List<Integer> aList = new ArrayList<>();
        List<Integer> lList = new LinkedList<>();
    }
}

//Creating arraylist example 
ArrayList<String> list = new ArrayList<String>();  
 
//Adding objects in arraylist 
list.add("Mango");    
list.add("Banana");   

//Change the element (index,"new value")
list.set(1,"Dates"); 

//Return the 2nd element, because index starts from 0
System.out.println("Returning element: " + list.get(1));
