Conclusion

So far you've covered the basics of networking with MIDP, as well as some of the more advanced topics you'll need to handle when developing more sophisticated multiplayer games. As you can see, there's quite a bit more to multiplayer gaming. (Let's not get into massively-multiplayer or persistent-world issuesI could probably write a book on one of those subjects alone.) However, multiplayer games are one of the most exciting areas of mobile game development. I have no doubt that the most successful J2ME games of the future will utilize both the mobile and connected natures of the devices.
