Java Timestamp valueOf() Method

The valueOf() method of Timestamp class converts the string object to Timestamp value or obtains an instance of Timestamp from a LocalDateTime object.

Syntax

public static Timestamp valueOf (String s)
public static Timestamp valueOf (LocalDateTime  dateTime)

Parameters

Here parameter 's' and 'dateTime' represent a string value in date-time format and a LocalDateTime value .

Returns

The valueOf() method of Timestamp class returns a Timestamp value.

Throws

The valueOf () method of Timestamp class throws:

IllegalArgumentException- if the given string argument is not in date-time(yyyy-mm-dd hh:mm:ss) format.

NullPointerException- if datetime is null.

Example 1

import java.sql.Timestamp;
public class JavaTimestampValueOfExample1 {
    public static void main(String[] args) {
        String str ="2018-09-01 09:01:15";
        System.out.println("String : "+str);
        // returns a Timestamp value corresponding to the given string
        Timestamp timestamp= Timestamp.valueOf(str);
        System.out.println("value of Timestamp : "+timestamp);
    }
}

Test it Now

Output:

String : 2018-09-01 09:01:15
value of Timestamp : 2018-09-01 09:01:15.0

Example 2

import java.sql.Timestamp;
public class JavaTimestampValueOfExample2 {
    public static void main(String[] args) {
        /*string should be in date-time(yyyy-mm-dd hh:mm:ss) format
        else it will give you same error like occurring below*/
        String str ="2018-09-01";
        System.out.println("String : "+str);
        // returns a Timestamp value corresponding to the given string
        Timestamp timestamp= Timestamp.valueOf(str);
        System.out.println("value of Timestamp : "+timestamp);
    }
}

Test it Now

Output:

String : 2018-09-01
Exception in thread "main" java.lang.IllegalArgumentException: Timestamp format must be yyyy-mm-dd hh:mm:ss[.fffffffff]
	at java.sql.Timestamp.valueOf(Timestamp.java:204)
	at JavaTimestampValueOfExample2.main(JavaTimestampValueOfExample2.java:7)

Example 3

import java.sql.Timestamp;
import java.time.LocalDateTime;
public class JavaTimestampValueOfExample3 {
    public static void main(String[] args) {
        LocalDateTime dateTime= null;
        // returns a Timestamp value corresponding to the given LocalDateTime
        Timestamp timestamp= Timestamp.valueOf(dateTime);
        System.out.println("value of Timestamp : "+timestamp);
    }
}

Test it Now

Output:

Exception in thread "main" java.lang.NullPointerException
	at java.sql.Timestamp.valueOf(Timestamp.java:551)
	at JavaTimestampValueOfExample3.main(JavaTimestampValueOfExample3.java:8)

Example 4

import java.sql.Timestamp;
import java.time.LocalDateTime;
public class JavaTimestampValueOfExample4 {
    public static void main(String[] args) {
        Timestamp timestamp = new Timestamp(System.currentTimeMillis());
        // returns a Timestamp value corresponding to the given LocalDateTime
        LocalDateTime dateTime= timestamp.toLocalDateTime();
        System.out.println("value of Timestamp : "+dateTime);
    }
}

Test it Now

Output:

value of Timestamp : 2018-09-06T12:04:44.386
