Java sql.Date setTime() method with example.

JDBCJava 8Object Oriented ProgrammingProgramming

The setTime() method of the java.util.Date class accepts a variable of long type, representing the number of milliseconds from the epoch time (January 1, 1970 00:00:00.000 GMT) to the required time, and sets the specified time value to the current Date object.

//Setting time
date.setTime(time_value_in_long);

Example

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 example inserts a new record into the dispatches table by passing the required values.

import java.sql.Connection;
import java.sql.Date;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.sql.Time;
public class Date_setTime {
   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......");
      //Instantiating the Time class
      Date date = new Date(0L);
      //Setting time
      date.setTime(new java.util.Date().getTime());
      //Creating a Prepared Statement
      String query = "INSERT INTO Dispatches VALUES (?, ?, ?, ?, ?, ?)";
      PreparedStatement pstmt = con.prepareStatement(query);
      pstmt.setString(1, "Watch");
      pstmt.setString(2, "Rajan");
      pstmt.setDate(3, date);
      pstmt.setTime(4, new Time(date.getTime()));
      pstmt.setInt(5, 4000);
      pstmt.setString(6, "Chennai");
      pstmt.execute();
      System.out.println("Rows inserted ....");
      //Retrieving values
      Statement stmt = con.createStatement();
      ResultSet rs = stmt.executeQuery("select * from dispatches");
      while(rs.next()) {
         System.out.println("Product Name: "+rs.getString("ProductName"));
         System.out.println("Customer Name: "+rs.getString("CustomerName"));
         System.out.println("Date Of Dispatch: "+rs.getDate("DispatchDate"));
         System.out.println("Delivery Time: "+rs.getTime("DeliveryTime"));
         System.out.println("Location: "+rs.getString("Location"));
         System.out.println();
      }
   }
}

Here, in this program we have instantiated a Date class by passing 0L to its constructor (epoch time:1970-01-01 05:30:00.0) and changed its time to current time using the setTime() method.

And we are trying to insert this time value under the DeliveryTime column in this record.

Output

Connection established......
