一个模拟器中的java元组数据结构

Question

我想创建一个名为Neighbor的元组数据结构，但有一个错误“（和[expected]，在我添加（）或[]之后仍然是一个错误，你能帮我吗

这里是源代码

protected Tuple<Map<DTNHost, Set<DTNHost>>,ArrayList<Double>> neighborhood;


protected SimBetRouterWithFairRouting(SimBetRouterWithFairRouting proto) {      

    neighboursNode = new HashMap<DTNHost, Set<DTNHost>>();
    indirectNode= new ArrayList<DTNHost>();
    directNode= new ArrayList<DTNHost>();
    this.rLambda = proto.rLambda;
    this.rSigma = proto.rSigma;
    this.a = proto.a;
    this.centrality = proto.centrality.replicate();
    this.similarity = proto.similarity.replicate();
    neighborsHistory = new HashMap<DTNHost, ArrayList<Double>>();

//这里是错误

neighborhood = new Tuple<HashMap<DTNHost, Set<DTNHost>>, ArrayList<Double>>;
}
