Java LocalTime isBefore() and isAfter() Method Example

This example shows how to compare time in Java using LocalTime class isBefore() and isAfter() Methods.

The java.time.LocalTime class is an immutable class which represents a time without time-zone information.

Java LocalTime isBefore() and isAfter() Method Example

LocalTime class provides below APIs to compare LocalTime objects in Java.
  • int compareTo(LocalTime other) - Compares this time to another time.
  • boolean isAfter(LocalTime other) - Checks if this time is after the specified time.
  • boolean isBefore(LocalTime other) - Checks if this time is before the specified time.
import java.time.LocalTime;

public class LocalTimeExample {
 
    public static void main(String[] args) {
        compareLocalTimeObjects();
    }

    private static void compareLocalTimeObjects() {
        LocalTime localTime1 = LocalTime.of(9, 10, 50);
        LocalTime localTime2 = LocalTime.of(9, 10, 50);
        LocalTime localTime3 = LocalTime.of(11, 45, 20);
  
        // compareTo() example
        if (localTime1.compareTo(localTime2) == 0) {
            System.out.println("localTime1 and localTime2 are equal");
        } else {
            System.out.println("localTime1 and localTime2 are not equal");
        }

        // isBefore() example
        if (localTime2.isBefore(localTime3)) {
             System.out.println("localTime2 comes before localTime3");
        }

        // isAfter() example
        if (localTime3.isAfter(localTime1)) {
            System.out.println("localTime3 comes after localTime1");
        }
    }
}
Output:
localTime1 and localTime2 are equal
localTime2 comes before localTime3
localTime3 comes after localTime1
