            writer.flush();//将缓存区内容压入文件
            writer.close();
                   
            
            
        
        
        
  
    } catch (IOException e) {
        e.printStackTrace();
    }
  

}

public static void main(String[] args) {
    
    String nowDate = "20221002";
    
    for (int j = 0; j < headStrings.length; j++) {
        for (int i = 0; i < sit.length; i++) {
            txtString(sit[i],nowDate,headStrings[j]);
       }
    }
        
    
}

}
