public class AbstractSequentialListDemo1 { 
    public static void main(String[] args) 
    { 
AbstractSequentialList<Integer> a = new LinkedList<>(); 
a.add(1); 
a.add(2); 
a.add(3); 
a.add(4);         
a.add(5); 
a.add(6); 
System.out.println("List = "+a); 
	System.out.println("************************************");
	System.out.println("The 2nd elements in the List is: "+ a.get(2)); 
	System.out.println("************************************");
	System.out.println("Remove 3rd element from the list: "+a.remove(3));    
	System.out.println("************************************");
