JAVA PriorityQueue实现定制排序

import java.util.*;
public class Test
{
public static void main(String[] args){
PriorityQueue<String> pq=new PriorityQueue<String>(10,new Comparator()   //定义一个匿名内部类
{
public int compare(Object obj1,Object obj2){
String s1=(String)obj1;
String s2=(String)obj2;
if(s1.length()>s2.length())
return 1;
else if(s1.length()<s2.length())
return -1;
else
return 0;
}

});
pq.add("chensongxia");
pq.add("yuyue");
pq.offer("qiandanping");
for(String str:pq){
System.out.println(str);
}
}
}
