  • Last Updated : 29 Apr, 2019

minus(long, TemporalUnit) method of a ChronoLocalDate interface used to Returns a copy of this ChronoLocalDate with the specified amount of unit subtracted to ChronoLocalDate.If it is not possible to subtract the amount, because the unit is not supported or for some other reason, an exception is thrown.

Syntax:

public ChronoLocalDate minus(long amountToSubtract,
                       TemporalUnit unit)

Parameters: This method accepts two parameters:

  • amountToSubtract: which is the amount of the unit to subtract to the result, may be negative
  • unit: which is the unit of the amount to subtract.

Return value: This method returns ChronoLocalDate based on this date-time with the specified amount subtracted.

Exception: This method throws following Exceptions:



  • DateTimeException: if the subtraction cannot be made
  • UnsupportedTemporalTypeException: if the unit is not supported
  • ArithmeticException: if numeric overflow occurs

Below programs illustrate the minus() method:

Program 1:




// Java program to demonstrate
// ChronoLocalDate.minus() method
  
import java.time.*;
import java.time.temporal.*;
import java.time.chrono.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create a ChronoLocalDate object
        ChronoLocalDate zonedlt
            = LocalDate.parse("2018-12-06");
  
        // subtract 12 Years to ChronoLocalDate
        ChronoLocalDate value
            = zonedlt.minus(12, ChronoUnit.YEARS);
  
        // print result
        System.out.println("ChronoLocalDate after "
                           + "subtracting Months: "
                           + value);
    }
}
Output:
ChronoLocalDate after subtracting Months: 2006-12-06
