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 subtraction 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
