How do I iterate through an array in Java?

How do I iterate through an array in Java?

You can use a for loop to iterate through an array in Java. For example:

int[] numbers = {1, 2, 3, 4, 5};
for (int i = 0; i < numbers.length; i++) {
    System.out.println(numbers[i]);
}

Can I use an enhanced for loop instead?

Yes, you can use the enhanced for loop (also known as the for-each loop) for simpler syntax:

for (int number : numbers) {
    System.out.println(number);
}

What if I want to modify the elements while iterating?

If you want to modify elements, you should use a regular for loop to access the index:

for (int i = 0; i < numbers.length; i++) {
    numbers[i] *= 2; // Example modification
}
