Often an array is iterated through to perform some operation on each element in it.
Usually a for-loop is used in such a case, but it’s also possible to use other types of loop statements as shown in the example below where a character array is looped through and each element is printed out:

        char[] letters = new char[] { 'j', 'a', 'v', 'a', 'd', 'b', '.', 'c', 'o', 'm' };

        for (int i = 0; i < letters.length; i++) {
            System.out.print(letters[i]);
        }
        System.out.println(); //new line

        for (char c : letters) {
            System.out.print(c);
        }
        System.out.println(); //new line

        int i1 = 0;
        while (i1 < letters.length) {
            System.out.print(letters[i1++]);
        }

They all of course produce the same result:
