Get first and last elements

Report a typo

Write a method named getFirstAndLast. The method must take an array of ints and return a new array of ints. The returned array must contain two elements: the first and the last elements of the input array.

It is guaranteed that the input array always has at least one element.

Sample Input 1: 

1 2 3 4

Sample Output 1: 

1 4
Write a program in Java 17
import java.util.*;

public class Main {

// write a method here

/* Do not change code below */
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int[] array = Arrays.stream(scanner.nextLine().split(" "))
.mapToInt(Integer::parseInt)
.toArray();
int[] result = getFirstAndLast(array);
Arrays.stream(result).forEach(e -> System.out.print(e + " "));
}
}
