int number = 110101; 
String temp = Integer.toString(number);
int[] numbers = new int[temp.length()];
for (int i = 0; i < temp.length(); i++) {
    numbers[i] = temp.charAt(i) - '0';
}

int

int[] primitiveArray = { 1, 2, 3, 4, 5 };
 
Integer[] boxedArray = Arrays.stream(primitiveArray) // IntStream
  .boxed()                // Stream<Integer>
  .toArray(Integer[]::new);

System.out.println(Arrays.toString(boxedArray));
