priority queue in C++ to java

Question

could anyone please tell me how to write this priority queue (written in C++) using Java

priority_queue< pair< int, Hole >, vector< pair< int, Hole > >, Hole::CompH > moves;

the CompH is a struct:

   struct CompH {
                bool operator()(const pair< int, Hole >& lhs, const pair< int, Hole >& rhs) const
                {
                        return lhs.second.getH() < rhs.second.getH();
                }
        };

I want to understand this part so I can write it in Java, Please. Thanks

Don't use C++ code to figure out how to write Java code. The same thing can be said about using Java code to figure out how to write C++ code -- don't do it. — PaulMcKenzie, May 11 '14 at 22:20

The CompH is directly analogous to a java.util.Comparator, and the PQ class itself is java.util.PriorityQueue.
