1：排序类

package com.tixa.bad.customer.util;

import java.util.ArrayList;

import java.util.Collections;

import java.util.Comparator;

import com.tixa.bad.customer.data.AdstatGraphArea;

/**

* 对地区数据进行排序

*

* @StatAreaSort

*

* @author

*

* TODO

*/

public class StatAreaSort

{

/**

* 点击排序规则，倒序

*/

private static Comparator orderClick = new Comparator()

{

public int compare(Object o1, Object o2)

{

AdstatGraphArea b1 = (AdstatGraphArea) o1;

AdstatGraphArea b2 = (AdstatGraphArea) o2;

return (b2.getClickcount() - b1.getClickcount());

}

};

/**

* ip排序规则，倒序

*/

private static Comparator orderIP = new Comparator()

{

public int compare(Object o1, Object o2)

{

AdstatGraphArea b1 = (AdstatGraphArea) o1;

AdstatGraphArea b2 = (AdstatGraphArea) o2;

return (b2.getIpcount() - b1.getIpcount());

}

};

/**

* 根据点击量进行排序

*

* @param list

*/

public static void getSortClick(ArrayList list)

{

Collections.sort(list, orderClick);

// Collections.reverse(list);

}

/**

* 根据ip量进行排序

*

* @param list

*/

public static void getSortIp(ArrayList list)

{

Collections.sort(list, orderIP);

// Collections.reverse(list);

}

}

2：对排序进行测试

package com.tixa.bad.customer.util;

import java.util.ArrayList;

import junit.framework.TestCase;

import com.tixa.bad.customer.data.AdstatGraphArea;

public class StatAreaSortTest extends TestCase

{

protected void setUp() throws Exception

{

super.setUp();

}

protected void tearDown() throws Exception

{

super.tearDown();

}

/*

* Test method for 'com.tixa.bad.customer.util.StatAreaSort.getSortClick(ArrayList)'

*/

public void testGetSortClick()

{

ArrayList list = new ArrayList();

AdstatGraphArea graAre = new AdstatGraphArea();

graAre.setAdid(1);

graAre.setClickcount(786);

graAre.setIpcount(43453);

list.add(graAre);

AdstatGraphArea graAre1 = new AdstatGraphArea();

graAre1.setAdid(2);

graAre1.setClickcount(987876);

graAre1.setIpcount(545);

list.add(graAre1);

AdstatGraphArea graAre2 = new AdstatGraphArea();

graAre2.setAdid(3);

graAre2.setClickcount(877887);

graAre2.setIpcount(4534534);

list.add(graAre2);

AdstatGraphArea graAre3 = new AdstatGraphArea();

graAre3.setAdid(4);

graAre3.setClickcount(97998);

graAre3.setIpcount(34534);

list.add(graAre3);

AdstatGraphArea graAre4 = new AdstatGraphArea();

graAre4.setAdid(5);

graAre4.setClickcount(500);

graAre4.setIpcount(2000);

list.add(graAre4);

System.out.print("sore before ");

for(int i = 0;i

{

AdstatGraphArea a = (AdstatGraphArea)list.get(i);

System.out.println(a.getAdid());

}

StatAreaSort.getSortClick(list);

System.out.print("sore after");

for(int i = 0;i

{

AdstatGraphArea a = (AdstatGraphArea)list.get(i);

System.out.println(a.getAdid());

}

System.out.println("----------------------");

StatAreaSort.getSortIp(list);

for(int i = 0;i

{

AdstatGraphArea a = (AdstatGraphArea)list.get(i);

System.out.println(a.getAdid());

}

}

/*

* Test method for 'com.tixa.bad.customer.util.StatAreaSort.getSortIp(ArrayList)'

*/

public void testGetSortIp()

{

}

}
