1. Mutability –
Arrays.asList is mutable which means that you cannot add or remove elements from the list.
However, you can modify the existing elements in the list.
Example –
String[] array = {"apple", "banana", "cherry"};
List<String> list = Arrays.asList(array);
list.set(0, "orange"); // Changes "apple" to "orange"
List.of is immutable, meaning you cannot add, remove or modify elements in the list.
If you try to modify the list, you will get an UnsupportedOperationException
Example – Creates a new instance of the List interface.
List<String> list = List.of("apple", "banana", "cherry");
list.set(0, "orange"); // Throws UnsupportedOperationException
2. Null Element –
Arrays.asList Allow null Element
Example –
String[] array = {"apple", null, "cherry"};
List<String> list = Arrays.asList(array); // Allowed
List.of does not Allow Null Element
Example –
List<String> list = List.of("apple", null, "cherry"); // Throws NullPointerException
