import java.util.ArrayList;

int[] primitiveArray = {1, 2, 3, 4, 5};

// Use Arrays.stream() to convert the int[] to an IntStream, then collect it
ArrayList<Integer> arrayList = Arrays.stream(primitiveArray)
                                     .boxed() // Converts int to Integer
                                     .collect(Collectors.toCollection(ArrayList::new));

System.out.println(arrayList); // Output: [1, 2, 3, 4, 5]
