How can I enter ResultSets while loop so that all of the records will be given the Date value.
import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.PreparedStatement;
 

public class DemoPreparedStatementSetDate {

  public static java.sql.Date getCurrentJavaSqlDate() {

    java.util.Date today = new java.util.Date();

    return new java.sql.Date(today.getTime());

  }
 

  public static Connection getConnection() throws Exception {
 

    String url = "jdbc:mysql://localhost/datedb";

    String username = "root";

    String password = "root";

    Connection conn = DriverManager.getConnection(url, username, password);

    return conn;

  }
 

  public static void main(String[] args) throws Exception {

    Connection conn = null;

    PreparedStatement pstmt = null;

    try {

      conn = getConnection();

      String query = "insert into datetable(id, date_column) values(?, ?)";

      pstmt = conn.prepareStatement(query);

      pstmt.setString(1, "0001");

      java.sql.Date date = getCurrentJavaSqlDate();

      pstmt.setDate(2, date);
 

      // execute query, and return number of rows created

      int rowCount = pstmt.executeUpdate();

      System.out.println("rowCount=" + rowCount);

    } finally {

      pstmt.close();

      conn.close();

    }

  }

}

 String query = "update datetable set date_column=? where id =?";

      pstmt = conn.prepareStatement(query);

       java.sql.Date date = getCurrentJavaSqlDate();
 

      pstmt.setDate(1, date);

      pstmt.setString(2, "0001");

 

      // execute query, and return number of rows created

      int rowCount = pstmt.executeUpdate();
