本文实例为大家分享了java数独游戏的具体代码，供大家参考，具体内容如下
打算把javaFx需要的组件装好以后直接用javaFx的，但似乎eclipse的版本不对，安装了也不能用...
数独代码是在之前寒假受命写的，学了一个月java的成果，现在看来有些不足但毕竟是第一个程序，就直接放上来，数独终盘的实现直接用了暴力，时间复杂度有点高，懒得改了直接放代码
终盘实现：
import java.util.Random; public class SudokuPuzzleGenerator { private Random random = new Random(); private static final int MAX_CALL_RANDOM_ARRAY_TIMES = 220; private int currentTimes = 0; public int[][] generatePuzzleMatrix() { int[][] randomMatrix = new int[9][9]; for (int row = 0; row < 9; row++) { if (row == 0) { currentTimes = 0; randomMatrix[row] = buildRandomArray(); } else { int[] tempRandomArray = buildRandomArray(); for (int col = 0; col < 9; col++) { if (currentTimes < MAX_CALL_RANDOM_ARRAY_TIMES) { if (!isCandidateNmbFound(randomMatrix, tempRandomArray, row, col)) { resetValuesInRowToZero(randomMatrix,row); row -= 1; col = 8; tempRandomArray = buildRandomArray(); } } else { row = -1; col = 8; resetValuesToZeros(randomMatrix); currentTimes = 0; } } } } return randomMatrix; } private void resetValuesInRowToZero(int[][] matrix, int row) { for (int j = 0; j < 9; j++) { matrix[row][j] = 0; } } private void resetValuesToZeros(int[][] matrix) { for (int row = 0; row < 9; row++) { for (int col = 0; col < 9; col++) { matrix[row][col] = 0; } } } private boolean isCandidateNmbFound(int[][] randomMatrix, int[] randomArray, int row, int col) { for (int i = 0; i < 9; i++) { randomMatrix[row][col] = randomArray[i]; if (noConflict(randomMatrix, row, col)) { return true; } } return false; } private boolean noConflict(int[][] candidateMatrix, int row, int col) { return noConflictInRow(candidateMatrix, row, col)&&noConflictInColumn(candidateMatrix, row, col) && noConflictInBlock(candidateMatrix, row, col); } private boolean noConflictInRow(int[][] candidateMatrix, int row, int col) { int currentValue = candidateMatrix[row][col]; for (int colNum = 0; colNum < col; colNum++) { if (currentValue == candidateMatrix[row][colNum]) { return false; } } return true; } private boolean noConflictInColumn(int[][] candidateMatrix, int row, int col) { int currentValue = candidateMatrix[row][col]; for (int rowNum = 0; rowNum < row; rowNum++) { if (currentValue == candidateMatrix[rowNum][col]) { return false; } } return true; } private boolean noConflictInBlock(int[][] candidateMatrix, int row, int col) { int baseRow = row / 3 * 3; int baseCol = col / 3 * 3; for (int rowNum = 0; rowNum < 8; rowNum++) { if (candidateMatrix[baseRow + rowNum / 3][baseCol + rowNum % 3] == 0) { continue; } for (int colNum = rowNum + 1; colNum < 9; colNum++) { if (candidateMatrix[baseRow + rowNum / 3][baseCol + rowNum % 3] == candidateMatrix[baseRow + colNum / 3][baseCol + colNum % 3]) { return false; } } } return true; } private int[] buildRandomArray() { currentTimes++; int[] array = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9 }; int randomInt = 0; for (int i = 0; i < 20; i++) { randomInt = random.nextInt(8) + 1; int temp = array[0]; array[0] = array[randomInt]; array[randomInt] = temp; } return array; } public int getCurrentTimes() { return currentTimes; } public void setCurrentTimes(int currentTimes) { this.currentTimes = currentTimes; } } 界面及判断:
