如何在Java中返回3x6矩阵的所有可能结果？

public class MatrixGenerator {
    public static void main(String[] args) {
        int rows = 3;
        int cols = 6;
        generateMatrices(rows, cols, new int[rows][cols], 0, 0);
    }

    private static void generateMatrices(int rows, int cols, int[][] matrix, int currentRow, int currentCol) {
        if (currentRow == rows) {
            printMatrix(matrix);
            return;
        }
        if (currentCol == cols) {
            generateMatrices(rows, cols, matrix, currentRow + 1, 0);
            return;
        }
        for (int i = 0; i <= 1; i++) { // 假设每个位置只能是0或1
            matrix[currentRow][currentCol] = i;
            generateMatrices(rows, cols, matrix, currentRow, currentCol + 1);
        }
    }

    private static void printMatrix(int[][] matrix) {
        for (int[] row : matrix) {
            for (int val : row) {
                System.out.print(val + " ");
            }
            System.out.println();
        }
        System.out.println("--------------------");
    }
}
