First LinkedList is declared and initialized.

Code:

LinkedList <Integer> list = new LinkedList<Integer>();

Here you have to define the generic to avoid compiler warnings. Generic is depend on the LinkedList element type. Here it is an Integer. Then populate the linked list. You can do it in different ways.

Just add elements there.

Code:

list.add(new Integer(1));

Here actually no need to instantiate a int value. Simply add.

Code:

list.add(1);

Or you can define the index that where you want to add the element.

Code:

list.add(2, new Integer(0));

But you can't skip index there. Then remove element,

Code:

list.remove(0);

Remove the 0th element of the list.
