    public static void main(String[] args) {

        List < String > fruits = new ArrayList < > ();
        // Adding new elements to the ArrayList
        fruits.add("Banana");
        fruits.add("Apple");
        fruits.add("mango");
        fruits.add("orange");
        System.out.println(fruits);

        // using Java 8 copyOf() method
        List < String > copy = List.copyOf(fruits);
        System.out.println(copy);
    }
}
Output:
[Banana, Apple, mango, orange]
[Banana, Apple, mango, orange]
