当我为 aco 运行此代码时，出现错误 Uniform 无法解析为类型

Question

这里的代码..这显示了使用uniform时的错误，即uniform无法解析为一个类型。

private Uniform uniform;

    private final ExecutorService threadPool = Executors.newFixedThreadPool(poolSize);

    private final ExecutorCompletionService<WalkedWay> agentCompletionService = new ExecutorCompletionService<WalkedWay>(
                    threadPool);

    final double[][] matrix;
    final double[][] invertedMatrix;
    private final double[][] pheromones;
    private final Object[][] mutexes;

    public AntColonyOptimization() throws IOException {
            // read the matrix
            matrix = readMatrixFromFile();
            invertedMatrix = invertMatrix();
            pheromones = initializePheromones();
            mutexes = initializeMutexObjects();
            // (double min, double max, int seed)
            uniform = new Uniform(0, matrix.length - 1, (int) System.currentTimeMillis());
    }

Answer 1

在声明部分添加这一行

private Uniform uniform ;
