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();
