将List转换为二维数组(result)

 

result的数据结构为List<Map<String,Object>>

 

            //将List转换为二维数组String[][]

              String[][] z = new String[result.size()][];  

              

                 for(int i=0;i<z.length;i++){

                  

                  Map m = (Map)result.get(i);

                  Set set = m.keySet();

                  z[i] = new String[m.size()];

                  Iterator it =set.iterator();

                

                 for(int j=0;it.hasNext();j++){

                     String s = (String)it.next();

                     if(m.get(s)!=null){

                         z[i][j] =m.get(s).toString();

                     }

                  }

              }
