            for (int j = i + 1; j < userNames.length; j++) {
                if (userNames[i].compareTo(userNames[j]) > 0) {

                    userNames[i] = userNames[j];
                    userNames[j] = temp;

        String[] names = {"Ram", "Mohan", "Sohan", "Rita", "Anita", "Nita", "Shyam", "Mukund"};
        System.out.println("Names before sort");
        for (String n : names) {
            System.out.print(" " + n);
        }
        String[] sortedNames = sortNames(names);
        System.out.println("\nNames after sort (Sent name)");
        for (String n : names) {
            System.out.print(" " + n);
        }
        System.out.println("\nNames after sort (Received name)");
        for (String n : sortedNames) {
            System.out.print(" " + n);
