Question

If you want to find the sum of all the numbers in an array of integers, what type of Java loop is most appropriate?

Select one:
a. enhanced for
b. while
c. for
d. do-while

Answer 1

The most appropriate type of loop to sum all numbers in an integer array in Java is the enhanced for loop, which is simpler and less error-prone for this task.

Step-by-step explanation:

If you want to find the sum of all the numbers in an array of integers in Java, the most appropriate type of loop to use would usually be the enhanced for loop (option a). This type of loop simplifies the syntax required to iterate through each element of the array. Here's an example of how you might write this:

int sum = 0;
for (int number : array) {
sum += number;
}

The enhanced for loop automatically goes through all the elements of the array array, adding each element's value to the sum variable. You don't have to manage the index or worry about the bounds of the array, which makes it less error-prone than a traditional for loop under these circumstances.
