TimestampDemo.java

import java.sql.Timestamp;
import java.time.LocalDateTime;

public class TimestampDemo
{

    public static void main(String[] args)
    {

        LocalDateTime localDateTime = LocalDateTime.now();
        System.out.println("localDateTime = " + localDateTime);

        /*
         * Obtains an instance of Timestamp from a LocalDateTime
         * object, with the same year, month, day of month, hours,
         * minutes, seconds and nanos date-time value as the provided
         * LocalDateTime
         */

        Timestamp timestamp = Timestamp.valueOf(localDateTime);
        System.out.println(timestamp);

        /*
         * Parameters:
         *
         * s - timestamp in format yyyy-[m]m-[d]d hh:mm:ss[.f...]. The
         * fractional seconds may be omitted. The leading zero for mm
         * and dd may also be omitted.
         *
         * Returns:
         *
         * corresponding Timestamp value
         */

        timestamp = Timestamp.valueOf("2013-01-23 19:09:58.743");
        System.out.println(timestamp);
    }

}

Output

localDateTime = 2018-11-13T09:59:07.900
2018-11-13 09:59:07.9
2013-01-23 19:09:58.743
