join轮换

join替换

需要jar包：commons-lang-2.4.jar

package org.cric.comm;

import java.util.ArrayList;

import org.apache.commons.lang.StringUtils;

public class JoinText {

 /**
  * @param args
  */
 public static void main(String[] args) {
  // TODO Auto-generated method stub
    String advSwitch="66*0*0*0*0*0*0*0*0*0";

   String[] swithch=advSwitch.split("\\*");
   String adv=swithch[0];//得到对应类型的投放的广告id
   String[] advid=adv.split(";");
   //int id=Integer.parseInt(advid[0]);
   
   System.out.println(adv.length()+",,"+adv);
   if(advid.length==1 && adv.equals(String.valueOf(66))){//此广告位只有一个广告并且是要删除的广告
    swithch[0]= String.valueOf("0");
      String newSwitch=StringUtils.join(swithch, "*");
      System.out.println("新的开关为："+newSwitch);
    
   }else{//此广告位有多个广告并且包含要删除的广告
    ArrayList list2=new ArrayList();
      for(int ii=0;ii<advid.length;ii++){
       String advId=advid[ii];
       if(Integer.parseInt(advId)!=66){
       list2.add(advId);
       }
      }
     swithch[0]=StringUtils.join(list2,";");
     String newSwitch=StringUtils.join(swithch, "*");
    
   }
