#java

public class testClient {

public static void main(String[] args) {
  // TODO Auto-generated method stub
  List<String> arrayList = new ArrayList<String>();
  Map<String,String> map = new HashMap<String, String>();

  String a = "1 a 2 aa 3 aaa 4 aaaa 5 aaaaa wqeqweqwe";
  String[] split = a.split(" ");
  for(String b:split){
   if(b.length()>0){
    //System.out.println(b);
    arrayList.add(b);
   }
  }
  System.out.println("---"+arrayList.size()/2);
  for(int i = 0;i<arrayList.size()-1;i++){
   if(i%2 == 0){
    String memory = arrayList.get(i);
    String e_name = arrayList.get(i+1);
    map.put(e_name, memory);
   }
  }
  System.out.println(map);
  System.out.println(map.size());
  System.out.println(arrayList.get(arrayList.size()-1));
  for (Map.Entry<String, String> entry : map.entrySet()) {
   System.out.println("Key = " + entry.getKey() + ", Value = " + entry.getValue());
  }
}

}

结果：

wqeqweqwe
Key = aaa, Value = 3
Key = aaaa, Value = 4
Key = a, Value = 1
Key = aa, Value = 2
Key = aaaaa, Value = 5

前台：

ftl:

<#assign map = result>
            <#list map?keys as key>
            <tr class=b>
          <td>${map[key]}</td>
          <td> ${key} </td>
          <td> </td>
         </tr>
         </#list>
