Design of mine-sweeping games (Kjava original)

Generally, according to Java development model, this procedure is generally divided into three modules to develop. The following three: a master file operated by a program, that is, a MIDLET inheritance; an interface representation class, that is, a Canvas's inheritance, there should be some menus on the interface, such as new, exit, then you should need to implement it. CommandListener Message Listening (You can understand the Java's message listening to a thread, always like a good thing to see the eye, of course, what he can touch, when you receive the news, Will call an abstract function PUBLIC VOID COMMANDACTION (COMMAND C, DISPLAY D), and this abstract function allows us to handle the message received by his implementation, that is, the message response) The last is of course a logical unit that is independent of the interface. Here we define the logic of the entire game and do logic to separately separate. This is my biggest harvest in Java, huh, huh. From: Low-key Male, Time: 2003-10-25 23:28:00, ID: 2252869 | Edit first officially started the first lecture My idea is that the mine map is generally a rectangle, Because the phone's mobile phone looks abreastous, it is not necessary to move him, so I can fully represent the entire map with a two-dimensional array of A * B. There is a map of the map naturally in the map naturally, there is a part of the mine. In this case, it is better to / *** 20 logo This location is the mine * <= 10 number Indicates that the unopened square and the number of mines around *> = 10 indicates that the number that has been opened and the surrounding mine number * * / representation method is, and the logic is clear. I want to open a block, as long as he adds him 10.
