Overview
In this tutorial, we show you how to convert String to Date in Java JDK 8. The java.time Package is the base package of new Java 8 Date Time API. All the major base classes are part of this package, such as
LocalDate,
LocalTime,
LocalDateTime.
Using ISO_LOCAL_DATE format
package com.jackrutorial;
import java.time.LocalDate;
public class ConvertStringToDateJava8Example1 {
public static void main(String[] args) {
String date = "2018-06-01";
LocalDate localDate = LocalDate.parse(date);
System.out.println("Date in ISO_LOCAL_DATE format is: " + localDate);
}
}
Output
Date in ISO_LOCAL_DATE format is: 2018-06-01
Using dd-MMM-yyyy format. Example: 01-Jun-2018
package com.jackrutorial;
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
public class ConvertStringToDateJava8Example2 {
public static void main(String[] args) {
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd-MMM-yyyy");
String date = "01-Jun-2018";
LocalDate localDate = LocalDate.parse(date, formatter);
System.out.println("Date in dd-MMM-yyyy format is: " + formatter.format(localDate));
}
}
Output
Date in dd-MMM-yyyy format is: 01-Jun-2018
Using yyyy-MM-dd format. Example: 2018-06-01
package com.jackrutorial;
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
public class ConvertStringToDateJava8Example3 {
public static void main(String[] args) {
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");
String date = "2018-06-01";
LocalDate localDate = LocalDate.parse(date, formatter);
System.out.println("Date in yyyy-MM-dd format is: " + formatter.format(localDate));
}
}
Output
Date in yyyy-MM-dd format is: 2018-06-01
Using yyyy-MM-dd HH:mm:ss format. Example: 2018-06-01 23:59:59
package com.jackrutorial;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
public class ConvertStringToDateJava8Example4 {
public static void main(String[] args) {
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
String date = "2018-06-01 23:59:59";
LocalDateTime localDateTime = LocalDateTime.parse(date, formatter);
System.out.println("Date in yyyy-MM-dd HH:mm:ss format is: " + formatter.format(localDateTime));
}
}
Output
Date in yyyy-MM-dd HH:mm:ss format is: 2018-06-01 23:59:59
Using dd/MM/yyyy format. Example: 01/06/2018
package com.jackrutorial;
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
public class ConvertStringToDateJava8Example5 {
public static void main(String[] args) {
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd/MM/yyyy");
String date = "01/06/2018";
LocalDate localDate = LocalDate.parse(date, formatter);
System.out.println("Date in dd/MM/yyyy format is: " + formatter.format(localDate));
}
}
Output
Date in dd/MM/yyyy format is: 01/06/2018
Using dd/MM/yyyy HH:mm:ss format. Example: 01/06/2018
package com.jackrutorial;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
public class ConvertStringToDateJava8Example6 {
public static void main(String[] args) {
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd/MM/yyyy HH:mm:ss");
String date = "01/06/2018 23:59:59";
LocalDateTime localDateTime = LocalDateTime.parse(date, formatter);
System.out.println("Date in dd/MM/yyyy HH:mm:ss format is: " + formatter.format(localDateTime));
}
}
Output
Date in dd/MM/yyyy HH:mm:ss format is: 01/06/2018 23:59:59
Using E, MMM dd yyyy format. Example: Fri, Jun 01 2018
package com.jackrutorial;
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;
public class ConvertStringToDateJava8Example7 {
public static void main(String[] args) {
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("E, MMM dd yyyy");
String date = "Fri, Jun 01 2018";
LocalDate localDate = LocalDate.parse(date, formatter);
System.out.println("Date in 'E, MMM dd yyyy' format is: " + formatter.format(localDate));
}
}
Output
Date in 'E, MMM dd yyyy' format is: Fri, Jun 01 2018
Using E, MMM dd yyyy HH:mm:ss format. Example: Fri, Jun 01 2018 23:59:59
package com.jackrutorial;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
public class ConvertStringToDateJava8Example8 {
public static void main(String[] args) {
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("E, MMM dd yyyy HH:mm:ss");
String date = "Fri, Jun 01 2018 23:59:59";
LocalDateTime localDateTime = LocalDateTime.parse(date, formatter);
System.out.println("Date in 'E, MMM dd yyyy HH:mm:ss' format is: " + formatter.format(localDateTime));
}
}
Output
Date in 'E, MMM dd yyyy HH:mm:ss' format is: Fri, Jun 01 2018 23:59:59
Using EEEE, MMM dd, yyyy HH:mm:ss a format. Example: Friday, Jun 01, 2018 12:10:56 PM
package com.jackrutorial;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
public class ConvertStringToDateJava8Example9 {
public static void main(String[] args) {
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("EEEE, MMM dd, yyyy HH:mm:ss a");
String date = "Friday, Jun 01, 2018 12:10:56 PM";
LocalDateTime localDateTime = LocalDateTime.parse(date, formatter);
System.out.println("Date in 'EEEE, MMM dd, yyyy HH:mm:ss a' format is: " + formatter.format(localDateTime));
}
}
Output
Date in 'EEEE, MMM dd, yyyy HH:mm:ss a' format is: Friday, Jun 01, 2018 12:10:56 PM
Using java.time.Instant
package com.jackrutorial;
import java.time.Instant;
import java.time.ZoneId;
import java.time.ZonedDateTime;
public class ConvertStringToDateJava8Example10 {
public static void main(String[] args) {
Instant instant = Instant.now();
System.out.println("Current Timestamp = "+ instant);
ZonedDateTime zonedDateTime1 = instant.atZone(ZoneId.of("US/Alaska"));
System.out.println("Date in US/Alaska Time Zone a format is:" +zonedDateTime1);
ZonedDateTime zonedDateTime2 = instant.atZone(ZoneId.of("Europe/London"));
System.out.println("Date in Europe/London Time Zone a format is:" +zonedDateTime2);
}
}
Output
Current Timestamp = 2018-06-21T09:39:11.582Z
Date in US/Alaska Time Zone a format is:2018-06-21T01:39:11.582-08:00[US/Alaska]
Date in Europe/London Time Zone a format is:2018-06-21T10:39:11.582+01:00[Europe/London]
Using java.time.ZonedDateTime
package com.jackrutorial;
import java.time.LocalDate;
import java.time.ZonedDateTime;
import java.time.format.DateTimeFormatter;
public class ConvertStringToDateJava8Example11 {
public static void main(String[] args) {
String date = "2018-06-01T23:59:59+12:00";
ZonedDateTime zonedDateTime = ZonedDateTime.parse(date, DateTimeFormatter.ISO_DATE_TIME);
System.out.println("ZonedDateTime : " + zonedDateTime);
System.out.println("TimeZone : " + zonedDateTime.getZone());
LocalDate localDate = zonedDateTime.toLocalDate();
System.out.println("LocalDate : " + localDate);
}
}
Output
ZonedDateTime : 2018-06-01T23:59:59+12:00
TimeZone : +12:00
LocalDate : 2018-06-01
