Answer:
import java.util.Scanner;
public class Main
{
public static void main(String[] args) {
int[] arr = {4, 6, 9, 12};
int sum = 0;
for(int i=0; i<arr.length; i++){
sum += arr[i];
}
for(int i=0; i<arr.length; i++){
System.out.print(arr[i] + " ");
}
System.out.println("");
System.out.println("The sum of the numbers: " + sum);
}
}
Explanation:
* The code is written in Java.
- Initialize the array with the given numbers
- Initialize the <em>sum</em> variable as zero
- Calculate the sum in the first for loop
- Print the numbers in the second for loop
- Print the <em>sum</em>
