LocalDateTime equals() method in Java
The equality of two LocalDateTime objects can be determined using the equals() method in the LocalDateTime class in Java. This method requires a single parameter i.e. the LocalDateTime object to be compared. Also it returns true if both the LocalDateTime objects are equal and false otherwise.
A program that demonstrates this is given as follows −
Example
import java.time.*; public class Main { public static void main(String[] args) { LocalDateTime ldt1 = LocalDateTime.parse("2019-02-18T23:15:30"); LocalDateTime ldt2 = LocalDateTime.parse("2019-02-18T23:15:30"); System.out.println("The LocalDateTime ldt1 is: " + ldt1); System.out.println("The LocalDateTime ldt2 is: " + ldt2); boolean flag = ldt1.equals(ldt2); if(flag) System.out.println("
Both LocalDateTime objects are equal"); else System.out.println("
Both LocalDateTime objects are not equal"); } }
Output
The LocalDateTime ldt1 is: 2019-02-18T23:15:30 The LocalDateTime ldt2 is: 2019-02-18T23:15:30 Both LocalDateTime objects are equal
Now let us understand the above program.
The two LocalDateTime objects are displayed. It is checked if the LocalDateTime objects are equal using the equals() method. The returned value of the method is displayed using an if statement. A code snippet that demonstrates this is as follows −
LocalDateTime ldt1 = LocalDateTime.parse("2019-02-18T23:15:30"); LocalDateTime ldt2 = LocalDateTime.parse("2019-02-18T23:15:30"); System.out.println("The LocalDateTime ldt1 is: " + ldt1); System.out.println("The LocalDateTime ldt2 is: " + ldt2); boolean flag = ldt1.equals(ldt2); if(flag) System.out.println("
Both LocalDateTime objects are equal"); else System.out.println("
Both LocalDateTime objects are not equal");
