The minus() method of a ChronoLocalDateTime interface is used to return a copy of this ChronoLocalDateTime with the specified amount subtracted to date-time. The amount is typically Period or Duration but may be any other type implementing the TemporalAmount interface.
Syntax:
default ChronoLocalDateTime minus(TemporalAmount amountTosubtract)
Parameters: This method accepts one single parameter amountTosubtract which is the amount to subtract, It should not be null.
Return value: This method returns ChronoLocalDateTime based on this date-time with the subtractition made, not null.
Exception:
This method throws following Exceptions:
- DateTimeException – if the subtraction cannot be made
- ArithmeticException – if numeric overflow occurs
Below programs illustrate the minus() method:
Program 1:
// Java program to demonstrate // ChronoLocalDateTime.minus() method import java.time.*; import java.time.chrono.*; public class GFG { public static void main(String[] args) { // Get the ChronoLocalDateTime instance ChronoLocalDateTime ldt = LocalDateTime .parse("2019-12-31T19:15:30"); // Get the String representation // of this ChronoLocalDateTime System.out.println("Original ChronoLocalDateTime: " + ldt.toString()); // subtract 10 Days to ChronoLocalDateTime ChronoLocalDateTime value = ldt.minus(Period.ofDays(10)); // print result System.out.println("ChronoLocalDateTime after" + " subtracting Days: " + value); } } |
Original ChronoLocalDateTime: 2019-12-31T19:15:30 ChronoLocalDateTime after subtracting Days: 2019-12-21T19:15:30
