Iterating over arrays

There are different methods to iterate over arrays. We will have a look at the use of the traditional for loop and the enhanced for loop (also known as the for-each loop).

Using the for loop

We can use the traditional for loop to iterate over an array by using an index variable. The loop starts at index 0 and continues until the index reaches the length of the array. Here’s an example that demonstrates how to use a for loop to iterate over an array and print its elements:

int[] results = {10, 20, 30, 40, 50};for (int i = 0; i < results.length; i++) {
    System.out.println("Element at " + i + ": " +
      results[i]);
}

The output will be as follows:

Element at 0: 10Element at 1: 20
Element at 2: 30
Element at 3: 40
Element at 4: 50

At this point, we know enough to revisit the example that we saw at the beginning of the chapter, calculating the average of several...
