MySQL 데이터베이스에 빈 java.sql.Date를 삽입하는 더 우아한 방법은 무엇입니까?

mysql> create table DemoTable
(
   AdmissionDate date
);
Query OK, 0 rows affected (0.53 sec)

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
public class InsertNullDateDemo{
   public static void main(String[] args){
      Connection con=null;
      PreparedStatement ps=null;
      try{
         con=DriverManager.getConnection("jdbc:mysql://localhost:3306/web?useSSL=false", "root","123456");
         String query="insert into DemoTable(AdmissionDate) values(?) ";
         ps= con.prepareStatement(query);
         ps.setNull(1, java.sql.Types.DATE);
         ps.executeUpdate();
         System.out.println("check the table......");
      }
      catch(Exception e){
         e.printStackTrace();
      }
   }
}
