setTime()java.util.Time类的方法接受一个long类型的变量，该变量表示从纪元时间（1970年1月1日00：00：00.000 GMT）到所需时间的毫秒数，并将指定的时间值设置为当前时间对象
//设定时间 time.setTime(time_value_in_long);
让我们使用CREATE语句在MySQL数据库中创建一个带有名称调度的表，如下所示：
CREATE TABLE dispatches( ProductName VARCHAR(255), CustomerName VARCHAR(255), DispatchDate date, DeliveryTime time, Price INT, Location VARCHAR(255));
现在，我们将使用INSERT语句在分派表中插入5条记录-
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');以下JDBC示例通过传递所需的值将新记录插入到分派表中。
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 Time_setTime {
public static void main(String args[]) throws SQLException {
//注册驱动程序
DriverManager.registerDriver(new com.mysql.jdbc.Driver());
//获得连接
String mysqlUrl = "jdbc:mysql://localhost/mydatabase";
Connection con = DriverManager.getConnection(mysqlUrl, "root", "password");
System.out.println("Connection established......");
//实例化时间类
Time time = new Time(0L);
//设定时间
time.setTime(new java.util.Date().getTime());
//日期对象
Date date = new Date(time.getTime());
//创建一个准备好的语句
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, time);
pstmt.setInt(5, 4000);
pstmt.setString(6, "Chennai");
pstmt.execute();
System.out.println("Rows inserted ....");
//检索值
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();
}
}
}在这里，在此程序中，我们通过将0L传递给其构造函数（纪元时间：1970-01-01 05：30：00.0）来实例化Time类，并使用setTime()方法将时间更改为当前时间。
并且，我们通过传递上面创建的Time对象的时间值来创建Date对象，并将这些时间和日期值作为新记录的值插入。
输出结果
Connection established...... Rows inserted ....
