Question
Can you explain this problem to me,and what is happening?
![```java
int nums[] = {7, 2, 5, 8, 7, 2, 3, 4, 8};
int total = 0;
for (int n : nums) {
total += n;
}
System.out.println(total);
```
**Explanation:**
The code snippet initializes an array `nums` containing the integers {7, 2, 5, 8, 7, 2, 3, 4, 8}. It then sets an integer `total` to 0, which will hold the sum of the numbers in the array.
A for-each loop iterates through each element `n` in the `nums` array. Inside the loop, `total` is updated by adding the current element `n` to it. Finally, the total sum of the array is printed to the console.
**Task:**
Fill in the blank inside the loop with `total += n;` to calculate the sum of all elements in the `nums` array.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fef8944c1-efd3-4b85-a18e-90880dd3e09b%2F45bf6f36-9cc5-422e-a264-4fd2e9a8cdfe%2Fsul4w2_processed.png&w=3840&q=75)
