============================== Java 10 feature ============================== List.copyOf() method Java 10 introduced a new method called List.copyOf(). This method creates and unmodifiable copy of an existing list, meaning you can't change the list after you create it. This is useful when you want to share a list with others parts of your program, but ensure that the list cannot be modified. Key Points ============ Immutable copy : List.copyOf() creates a list that cannot be changed. Shallow copy : The elements themselves are not copied; only their references are. No Null Elements : The original list cannot containe null elements. Read only : Attempting to modify the list will result in an error. How to Use List.copyOf() To create an unmodifiable list, you can use the List.copyOf() method and pass and existing list to it. SYNTAX =========== List<Type> unmodifiable = List.copyOf(originalList); Here originalList is the list you want to copy, and unmodifiableList is the new list that cannot be modified.
