The isBefore() method of LocalDateTime class in Java checks if this date is before the specified date-time.
Syntax:
public boolean isBefore(ChronoLocalDateTime other)
Parameter: This method accepts a parameter other which is the other date-time to be compared to. It should not be null.
Returns: The function returns boolean value: if this date-time is before the specified date-time.
Below programs illustrate the LocalDateTime.isBefore() method:
Program 1:
Java
// Program to illustrate the isBefore() methodimport java.util.*;import java.time.*;public class GfG { public static void main(String[] args) { // Parses the date LocalDateTime dt1 = LocalDateTime .parse("2018-11-03T12:45:30"); // Prints the date System.out.println("Date 1: " + dt1); // Parses the date LocalDateTime dt2 = LocalDateTime .parse("2016-12-04T12:45:30"); // Prints the date System.out.println("Date 2: " + dt2); // Compares both dates System.out.println("Is Date 1 before Date 2: " + dt1.isBefore(dt2)); }} |
Output:
Date 1: 2018-11-03T12:45:30 Date 2: 2016-12-04T12:45:30 Is Date 1 before Date 2: false
Program 2:
Java
// Program to illustrate the isBefore() methodimport java.util.*;import java.time.*;public class GfG { public static void main(String[] args) { // Parses the date LocalDateTime dt1 = LocalDateTime .parse("2018-11-03T12:45:30"); // Prints the date System.out.println("Date 1: " + dt1); // Parses the date LocalDateTime dt2 = LocalDateTime .parse("2019-12-04T12:45:30"); // Prints the date System.out.println("Date 2: " + dt2); // Compares both dates System.out.println("Is Date 1 before Date 2: " + dt1.isBefore(dt2)); }} |
Output:
Date 1: 2018-11-03T12:45:30 Date 2: 2019-12-04T12:45:30 Is Date 1 before Date 2: true
