hey! i have made a List object as follows:

List error = new LinkedList();

and then as per my requirements, i have added strings in it. like error.add(); like this. so, now at some time, i want this list to be empty, so i was doing error=null; which is giving me error of null pointer exception. so please help me how to do this? how can i make this list as empty ?

Do you mean that you want to remove all of the values in the linklist?

you can use the remove() on all the indexes
