The plusHours() method of LocalTime class is used to add specified no of Hours value to this LocalTime and return the result as a LocalTime object. This instant is immutable. The calculation wraps around midnight.
Syntax:
public LocalTime plusHours(long hoursToAdd)
Parameters: This method accepts a single parameter hoursToAdd which is the value of hours to be added, it can be a negative value.
Return value: This method returns a LocalTime based on this time with the hours added.
Below programs illustrate the plusHours() method:
Program 1:
// Java program to demonstrate // LocalTime.plusHours() method import java.time.*; public class GFG { public static void main(String[] args) { // create a LocalTime object LocalTime time = LocalTime.parse( "19:34:50.63" ); // print LocalTime System.out.println( "LocalTime before addition : " + time); // added 3 hours using plusHours() LocalTime value = time.plusHours( 3 ); // print result System.out.println( "LocalTime after addition : " + value); } } |
LocalTime before addition : 19:34:50.630 LocalTime after addition : 22:34:50.630
Program 2:
// Java program to demonstrate // LocalTime.plusHours() method import java.time.*; public class GFG { public static void main(String[] args) { // create a LocalTime object LocalTime time = LocalTime.parse( "01:00:01" ); // print LocalTime System.out.println( "LocalTime before addition : " + time); // added -10 hours using plusHours() LocalTime value = time.plusHours(- 10 ); // print result System.out.println( "LocalTime after addition : " + value); } } |
LocalTime before addition : 01:00:01 LocalTime after addition : 15:00:01
