Question

If you want to print an array in reverse order, what type of Java loop is most appropriate?

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

Answer 1

To print an array in reverse order in Java, a for loop is most appropriate as it allows easy manipulation of the index to iterate backwards through the array.

Step-by-step explanation:

If you want to print an array in reverse order using Java, the most appropriate type of loop would be option a, a for loop. The for loop is ideal because it allows you to initialize the index to the last element of the array and decrement the index in each iteration. Each loop would print the element until the index reaches 0, effectively outputting the array in reverse. Below is an example of how you might structure this loop:

int[] myArray = {1, 2, 3, 4, 5};
for (int i = myArray.length - 1; i >= 0; i--) {
System.out.println(myArray[i]);
}

This code sets the starting index i to the last index of myArray, which is myArray.length - 1, and continues to execute the block of code within the for loop until i is no longer greater than or equal to 0, printing each element in reverse.
