数据结构队列的应用

?

package com.guxia;import java.util.*;public class Test2 {public static void main(String[] args) {Queue<Integer> queue = new PriorityQueue<Integer>(10,new Comparator<Integer>(){public int compare(Integer i,Integer j) {// TODO Auto-generated method stubint result = i%2-j%2;if(result==0)result = i-j;return result;}});for(int i=0;i<10;i++){queue.offer(i);}for(int i=0;i<10;i++){System.out.println(queue.poll());}}}

输出结果：0 2 4 6 8 1 3 5 7 9
