The past few days to try to write graphics program with the Java swing, while learning to write a simple Sudoku game, in the process of writing learned a lot about swing things, but also for the programming of the graphical program has a little bit of a simple understanding: Good its prior to the device, since the writing graphics program first to play an IDE skilled, do not care what the IDE, like wh

Only the filled cells need to b

Sudoku is a test of eyesight and logic of the small game, the key in the "single" word, can not be repeated, the block can not be repeated. Today I will introduce a "loop + recursion + backtracking" method to use Java program for us to complete Sudoku.The code is then explained:1 ImportJava.util.HashMap; 2 ImportJava.util.Map; 3 4 public classT2 {5 public static final int n=3; 6 public static voidMain (stri

Detailed designgame data structure designObviously, the only place where you need to store data is the nine map section.For maps, it is obvious that we can use two-dimensional array int [] [] game; To store the data in the map. However, although the two-dimensional array of int is straightforward, there are some inconveniences, such as the rich built-in processing method without the set. So, obviously, in the game map generation process, some auxiliary data we can adopt the

PrefaceSudoku This game most people have played, so the specific game itself is not described.See Baidu Encyclopedia: http://baike.baidu.com/subview/961/10842669.htmRules and ObjectivesThe rules of Sudoku are simple, that is, in each row, each column, each small Gongge area (3x3) can not appear duplicate numbers.First paste the approximate game interface looks like:Demand Function AnalysisFrom the learner's point of view,Practice, learn the MVC framew

Seek Sudoku, only ask to make an answer.Just beginning to understand test instructions wrong, think the answer is unique, so did not do it for a long time, found that the answer is not unique after using backtracking.

You must have heard of the Sudoku game. such as "Figure 1.png", the player needs to be based on the known number on the 9x9 disk, to infer all the remaining space figures, and meet each row, each column, each of the same color nine within the number contains 1-9, do not repeat. The answer to Sudoku is unique, so many solutions are also called no solutions. The figures in this figure are said to be the dif
