ช่วยคิดโจทย์ข้อนี้หน่อยนะค่ะ เขียนเกม Dragonball ใช้การ์ด + Priority queue

import java.util.Comparator;
import java.util.PriorityQueue;
public class pqr {
static class PQsort implements Comparator<Integer> {
public int compare(Integer one, Integer two) {
return two-one;
}
}
public static void main(String[] args) {
int[] ia = { 1, 11, 5, 3, 4, 7, 6, 9, 8 };
PQsort pqs = new PQsort();
PriorityQueue<Integer> pq2 = new PriorityQueue<Integer>(pqs);
for (int x : ia) {
pq2.offer(x);
}
System.out.println("pq2: " + pq2);
System.out.println("peek: " + pq2.peek());
System.out.println("poll: " + pq2.poll());
System.out.println("size: " + pq2.size());
System.out.println("pq2: " + pq2);
}
}
