Is There Any Correct Java Code Out There?

By James Elliott
August 5, 2009

Writing correct, concurrent code is really hard. Java makes it seem easier than it is, even when you think you're being careful.

By Haining Henry Zhang
June 12, 2009

In previous articles, we finished writing most of the code of the Pac-Man game. In article 3, we implemented a simple algorithm for the ghosts to catch the Pac-Man. The ghosts randomly decides in which direction they move. They do not chase the Pac-Man even they are very close to him. This makes the game less challenging. In fact, the behavior of the ghosts are the most tricky part of the game. According to Iwatani, the author of the original arcade game, he had designed each ghost with its own distinct personality in order to keep the game from becoming too difficult or boring to play. ( More info) However, there is generally no conclusion on what behavior of the ghosts are good for the players.
