如何将数组的数据直接放入PriorityQueue

Question

你如何将数组的数据直接放入PriorityQueue哪个实现Queue接口？

ContestantFilter [] contestantFilter = new ContestantFilter [50];
contestantFilter [0] = new ContestantFilter("Agnesy Pricillia","IF110026");
contestantFilter [1] = new ContestantFilter("Ellen Shie ","IF110103");
contestantFilter [2] = new ContestantFilter("Wilma Yue Gunawan","EL110021");
.................
.................

Queue<ContestantFilter> queue = new PriorityQueue<ContestantFilter>(1,
                new Comparator<ContestantFilter>() {
                     @Override
                    public int compare(ContestantFilter t1, ContestantFilter t2) {
                        return t1.getID().compareTo(t2.getID());}});

我试过

for(ContestantFilter c : contestantFilter ){ queue.add(c);}

但它很慢。

就像是 ：

queue = ((Queue<ContestantFilter >) Arrays.asList(contestantFilter );

铸造不起作用。

PriorityQueue#addAll创建队列实例后使用方法：

//... is a replacement for your custom Comparator<ContestantFilter>
Queue<ContestantFilter> queue = new PriorityQueue(...);
queue.addAll(Arrays.asList(contestantFilter));
