JavaBean的使用老是报错 网上找了半天也不知道怎么改

[JJ_alive]

Cannot make a static reference to the non-static method setArticle_id(int) from the type article这个是错误提示
public class search_article {
String sql="select * from article";
dbconnection conn=new dbconnection();
public List<article> getArticleList(){
List<article> articleList=new ArrayList<article>();
ResultSet rs=conn.excuteQuery(sql);
try {
article arc=new article();
article.setArticle_id(rs.getInt("id "));
这个是还未写完的代码，代码中并没有静态的static，所以这个错不知道该怎么改

[Defonds]

article.setArticle_id(rs.getInt("id "));

should be

arc.setArticle_id(rs.getInt("id "));
