Remove Item In ArrayList , Java.lang.UnsupportedOperationException

I want remove item in array list select location My code is List historylist = Arrays.asList(history); if (historylist.size()>=3){ System.out.print

Solution 1:

Change

List<String> historylist = Arrays.asList(history);

to

 List<String> historylist = new LinkedList (Arrays.asList(history));

and see this post why this error occur in case of List :

Why do I get an UnsupportedOperationException when trying to remove an element from a List?

Solution 2:

You cannot add or remove elements from the list returned by Arrays.asList because the list is backed by the original array. To create a list that you can modify, you can do this:

List<String> historylist = new ArrayList<String>(Arrays.asList(history));

Solution 3:

I believe Arrays.asList() creates is fixed-length, and so does not support removing.

Try using an implementation that supports removing like ArrayList instead.

Solution 4:

try this

 list.set(position,obj);
