作业

可编写下面的java程序：

package org.example;

public class SourceCodeOrientedModel {
    public static void main(String[] args) {
        int total = 41;
        int[] m = {9, 22, 9, 5, 7, 10, 17, 27};
        double[] k = {(double)2 / 9, (double)2 / 9, (double)1 / 8, (double)1 / 13, (double)1 / 12, (double)2 / 9, (double)2 / 11, (double)1 / 11};
        double[] p = {0.8, 0.6, 0.4, 0.2, 0.1, 0.01, 0.001};

        double[] weights = new double[m.length];
        for (int i = 0; i < m.length; i++) {
            weights[i] = (double)m[i] / total;
        }

        for (int i = 0; i < p.length; i++) {
            double trustworthiness = softwareTrustworthinessMeasureTna(weights, k, p[i]);
            System.out.println("For p = " + p[i] + ", the software trustworthiness measure is " + trustworthiness);
        }

    }

    public static double softwareTrustworthinessMeasureTna(double[] weights, double[] k, double p) {
        double result = 0.0;
        for (int i = 0; i < weights.length; i++) {
            result += weights[i] * Math.pow(10 * Math.pow(k[i], p), p);
        }
        return Math.pow(result, 1 / p);
    }
}
