下面代码中怎么接收参数呀?

Question

import java.sql.*;
import java.util.ArrayList;
import java.util.List;

public class Link {

   static PreparedStatement preparedStatement = null;
   static Connection connection = null;
     public static List baseQuery(String sql, Object... args) {
       List<Object> List = new ArrayList<>();
int length=args.length;
       try {
           //创建连接
           Link.createLink();
           Link.connection.setAutoCommit(false);
           connection.prepareStatement(sql);

           for (int i = 0; i < args.length; i++) {
               preparedStatement.setObject(i + 1, args[i]);
           }
           ResultSet resultSet = preparedStatement.executeQuery();
           //将数据加入到集合中,便于查询用ARRAYlIST接收
           while (resultSet.next()) {
               for (int i = 1; i <= args.length; i++) {
                   Object obj=resultSet.getObject(i);
               }

               Object obj = new Object(//参数怎么接收???);
               List.add(obj);
           }
           if (!(List.size() == 0)) {
               for (Object o : List
               ) {
                   System.out.println(o);
               }
           } else {
               System.out.println("EMPTY DATA;");
           }
       } catch (Exception e1) {
           e1.printStackTrace();
           System.out.println("网络繁忙请稍后再试");

       } finally {

           if (null != Link.connection) {
               try {
                   Link.connection.commit();
               } catch (SQLException ex) {
                   ex.printStackTrace();
               }
           }
           //释放连接
           closeLink(Link.connection);

       }

            //将数据加入到集合中,便于查询用ARRAYlIST接收
           /**while (resultSet.next()) {
               for (int i = 1; i <= args.length; i++) {
                   Object obj=resultSet.getObject(i);
               }
 
               Object obj = new Object(//参数怎么接收???);
               List.add(obj);
           }*/
            //修改部分
           if (resultSet.hasNext()) {
               for (int i = 1; i <= args.length; i++) {
                   Object obj=resultSet.getObject(i);
               }
           } else {
               System.out.println("EMPTY DATA;");
           }

          //或者修改为

               //Object obj = new Object(//参数怎么接收???);
               //List.add(obj);
           }
           if (!(List.size() == 0)) {
