如何在java中实现决策矩阵？

public class DecisionMatrix {
    public static void main(String[] args) {
        // 定义决策矩阵
        int[][] matrix = {
            {1, 2, 3},
            {4, 5, 6},
            {7, 8, 9}
        };

        // 实现决策逻辑
        int maxScore = Integer.MIN_VALUE;
        int bestDecision = -1;
        for (int i = 0; i < matrix.length; i++) {
            int score = 0;
            for (int j = 0; j < matrix[i].length; j++) {
                score += matrix[i][j];
            }
            if (score > maxScore) {
                maxScore = score;
                bestDecision = i;
            }
        }

        // 输出决策结果
        System.out.println("最佳决策方案是：" + bestDecision);
    }
}
