How to create Date object from String value in Java?
Using the SimpleDateFormat class
One of the constructors of this class accepts a String value representing the desired date format and creates SimpleDateFormat class. To parse/convert a string as a Date object −
- Instantiate this class by passing desired format string.
- Parse the date string using the parse() method.
Example
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class Sample {
public static void main(String args[]) throws ParseException {
String date_string = "2007-25-06";
//Instantiating the SimpleDateFormat class
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-dd-MM");
//Parsing the given String to Date object
Date date = formatter.parse(date_string);
System.out.println("Date value: "+date);
}
}
Output
Date value: Mon Jun 25 00:00:00 IST 2007
Using the LocalDate class
The parse() method of the LocalDate class accepts a String value representing a date and returns a LocalDate object.
Example
import java.time.LocalDate;
public class Test {
public static void main(String args[]) {
LocalDate date = LocalDate.parse("2007-12-03");
System.out.println(date);
}
}
Output
2007-12-03
Using the DateUtils class:
The DateUtils provides utility to format date you can find it in apache.commons package following is the maven dependency for the package −
<dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> <version>3.7</version> </dependency>
The parseDate() method of the DateUtils class accepts a format string and a date string as parameters and returns a Date object.
Example
import java.util.Date;
import org.apache.commons.lang3.time.DateUtils;
public class Test {
public static void main(String args[]) {
String dateInString = "07-06-2013";
Date date = DateUtils.parseDate(dateInString, "yyyy-MM-dd");
System.out.println(date);
}
}
Output
Sat Dec 03 00:00:00 IST 12
Using the Instant class
The parse() method of the java.time.Instant class accepts a date string as a parameter and returns an object (Instant) representing the given date.
Example
import java.time.Instant;
public class Test {
public static void main(String args[]) {
String dateInString = "2014-10-05T15:23:01Z";
Instant instant = Instant.parse(dateInString);
System.out.println(instant);
}
}
Output
