		// add new elements to linked list in java

		list.add("php");
		list.add("hello");
		
		// add new item to the end of the linked list in java
		list.addLast("lautturi");
		
		// add new item to the first position in the linked list in java
		list.addFirst("perl");
		
		// Insert item into list at the location with index 2
		list.add(2,"c");
		
		// print the list
		System.out.println(list);
		
		// remove the element from linked list by value
		list.remove("hello");
		
		// remove the element from linked list by index
		list.remove(3);
		
		// print the list after deleting elements
		System.out.println(list);
		
		// delete the first element from the linked list in java
		list.removeFirst();
		
		// delete the last element from the linked list in java
		list.removeLast();
		
		// get the element at the position 4+1(index 4)
		String str = list.get(3);
		
		// modify item of linked list in java
		list.set(3, "c sharp");
		
		// print the list 
		System.out.println(list);

	}
}

output:

[perl, java, c, python, js, php, hello, lautturi]
[perl, java, c, js, php, lautturi]
[java, c, js, c sharp]
