Why is the result like this?

Question

Java

Why are we changing the value of the List object changing the value of the names array?

String [] names = {"Tom", "Dick", "Harry"};
         List<String> list = Arrays.asList(names);
         list.set(0, "Sue");
         System.out.println(names[0]);

result: Sue

Answer 1

Because it Arrays.asList()returns an Array List instance using the passed array. That is, you simply wrapped the same data with an additional abstraction.

Answer 2

Well, because you are not changing the array, but the NEW list obtained from the array, and you do not touch the array itself.
