How to add elements in List when used Arrays.asList()

Question

We cannot perform <Collection>.add or <Collection>.addAll operation on collections we have obtained from Arrays.asList .. only remove operation is permitted.

So What if I come across a scenario where I require to add new Element in List without deleting previous elements in List?. How can I achieve this?

Answer 1

Create a new ArrayList using the constructor:

List<String> list = new ArrayList<String>(Arrays.asList("a", "b")); 

Answer 2

One way is to construct a new ArrayList:

List<T> list = new ArrayList<T>(Arrays.asList(...)); 

Having done that, you can modify list as you please.
