The isBefore() method of OffsetDateTime class in Java checks if this date is before the specified date-time and returns true if it is.
Syntax:
public boolean isBefore(OffsetDateTime other)
Parameter: This method accepts a single parameter other which checks if this date-time is before the another date-time.
Return Value: It returns true if this is before the other date-time, else it returns false.
Below programs illustrate the isBefore() method:
Program 1:
Java
// Java program to demonstrate the isBefore() method import java.time.OffsetDateTime;
import java.time.ZonedDateTime;
public class GFG {
public static void main(String[] args)
{
// Parses the date1
OffsetDateTime date1
= OffsetDateTime
.parse(" 2018 - 11 -12T13: 30 : 30 + 05 : 00 ");
// Parses the date2
OffsetDateTime date2
= OffsetDateTime
.parse(" 2018 - 12 -12T13: 30 : 30 + 05 : 00 ");
// Prints both dates
System.out.println("Date1: " + date1);
System.out.println("Date2: " + date2);
// Compare both
System.out.println("Date1 before Date2? "
+ date1.isBefore(date2));
}
} |
Output:
Date1: 2018-11-12T13:30:30+05:00 Date2: 2018-12-12T13:30:30+05:00 Date1 before Date2? true
Program 2:
Java
// Java program to demonstrate the isBefore() method import java.time.OffsetDateTime;
import java.time.ZonedDateTime;
public class GFG {
public static void main(String[] args)
{
// Parses the date1
OffsetDateTime date1
= OffsetDateTime
.parse(" 2018 - 12 -12T13: 30 : 30 + 05 : 00 ");
// Parses the date2
OffsetDateTime date2
= OffsetDateTime
.parse(" 2015 - 12 -12T13: 30 : 30 + 05 : 00 ");
// Prints both dates
System.out.println("Date1: " + date1);
System.out.println("Date2: " + date2);
// Compare both
System.out.println("Date1 before Date2? "
+ date1.isBefore(date2));
}
} |
Output:
Date1: 2018-12-12T13:30:30+05:00 Date2: 2015-12-12T13:30:30+05:00 Date1 before Date2? false
