Mapping a string input to int array using streams.

Streams.java

String[] words = new Scanner(System.in).nextLine().split(" ");
int[] intArray = Arrays.stream(words).mapToInt(Integer::parseInt).toArray();
System.out.println(Arrays.toString(intArray));

// Alternative

int[] intArray = Arrays.stream(new Scanner(System.in).nextLine().split(" "))
                .mapToInt(Integer::parseInt)
                .toArray();
