import java.util.Random;
public class SuperExcelTester {
    public static void main(String[] args) {
        Random rnd = new Random();
        String[] messages = {
            "files are equal",
            "files are not equal",
            "unexpected error"
        int index = rnd.nextInt(messages.length);
        System.out.println(messages[index]);
