Java sql.Time toString() method with example

The toString() method of the java.sql.Time class returns the JDBC escape format of the time of the current Time object as String variable.
i.e. using this method you can convert a Time object to a String.
//Retrieving the Time object
Time timeObj = rs.getTime("DeliveryTime");
//Converting the Time object to String format
String time = timeObj.toString();
Let us create a table with name dispatches in MySQL database using CREATE statement as follows −
CREATE TABLE dispatches(
   ProductName VARCHAR(255),
   CustomerName VARCHAR(255),
   DispatchDate date,
   DeliveryTime time,
   Price INT,
   Location VARCHAR(255));
Now, we will insert 5 records in dispatches table using INSERT statements −
insert into dispatches values('Key-Board', 'Raja', DATE('2019-09-01'), TIME('11:00:00'), 7000, 'Hyderabad');
insert into dispatches values('Earphones', 'Roja', DATE('2019-05-01'), TIME('11:00:00'), 2000, 'Vishakhapatnam');
insert into dispatches values('Mouse', 'Puja', DATE('2019-03-01'), TIME('10:59:59'), 3000, 'Vijayawada');
insert into dispatches values('Mobile', 'Vanaja', DATE('2019-03-01'), TIME('10:10:52'), 9000, 'Chennai');
insert into dispatches values('Headset', 'Jalaja', DATE('2019-04-06'), TIME('11:08:59'), 6000, 'Goa');
Following JDBC program establishes connection with the database and retrieves the contents of the dispatches table.
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.sql.Time;
public class Time_toString {
   public static void main(String args[]) throws SQLException {
      //Registering the Driver
      DriverManager.registerDriver(new com.mysql.jdbc.Driver());
      //Getting the connection
      String mysqlUrl = "jdbc:mysql://localhost/mydatabase";
      Connection con = DriverManager.getConnection(mysqlUrl, "root", "password");
      System.out.println("Connection established......");
      //Creating a Statement object
      Statement stmt = con.createStatement();
      //Query to retrieve the contents of the dispatches table
      String query = "select * from dispatches";
      //Executing the query
      ResultSet rs = stmt.executeQuery(query);
      while(rs.next()) {
         System.out.println("Product Name: "+rs.getString("ProductName"));
         System.out.println("Customer Name: "+rs.getString("CustomerName"));
         System.out.println("Dispatch Date: "+rs.getDate("DispatchDate"));
         Time timeObj = rs.getTime("DeliveryTime");
         //Converting the Time object to String format
         String time = timeObj.toString();
         System.out.println("Delivery time in String format: "+time);
         System.out.println("Location: "+rs.getString("Location"));
         System.out.println();
      }  
   }
}
Here, in this program while retrieving the column values we have converted the Delivery Time value from Time object to string format using the toString() method of the Time class and displayed it.
