        for (int i = 0; i < 40; i++) {
            words[i] = scanner.nextLine();
        }

        // Selection sort in descending order
        for (int i = 0; i < words.length - 1; i++) {
            int maxIndex = i;
            for (int j = i + 1; j < words.length; j++) {
                if (words[j].compareTo(words[maxIndex]) > 0) {
                    maxIndex = j;
                }
            }
            // Swap the found maximum element with the first element
            String temp = words[maxIndex];

How to learn from this program

First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.

Practice suggestion

After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
