Something I found and cleaned up a little bit

Mystery.java

import java.util.Random;

public class Mystery {

    public static void main(String[] args) {
        System.out.println(randomString(-229985452) + " " + randomString(-147909649));
    }

    private static String randomString(int code) {
        Random random = new Random(code);
        StringBuilder builder = new StringBuilder();
        while (true) {
            int c = random.nextInt(27);
            if (c == 0) break;
            builder.append((char)('`' + c));
        }
        return builder.toString();
    }
}
