LocalDate minus() method in Java with Examples

28 Jan, 2022
In LocalDate class, there are two types of minus() method depending upon the parameters passed to it. 
minus() method of a LocalDate class used to Returns a copy of this LocalDate with the specified amount of unit subtracted to LocalDate.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 LocalDate 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 LocalDate 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
// Java program to demonstrate// LocalDate.minus() method import java.time.*;import java.time.temporal.ChronoUnit; public class GFG {    public static void main(String[] args)    {         // create a LocalDate object        LocalDate zonedlt            = LocalDate.parse("2018-12-06");         // subtract 12 Years to LocalDate        LocalDate value            = zonedlt.minus(12, ChronoUnit.YEARS);         // print result        System.out.println("LocalDate after "                           + "subtracting Months: "                           + value);    }}
LocalDate after subtracting Months: 2006-12-06
 
minus() method of a LocalDate class used to returns a copy of this LocalDate with the specified amount subtracted to LocalDate.The amount is typically Period or Duration but may be any other type implementing the TemporalAmount interface.Syntax:  
public LocalDate 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 LocalDate 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
// Java program to demonstrate// LocalDate.minus() method import java.time.*;public class GFG {    public static void main(String[] args)    {         // create a LocalDate object        LocalDate zonedlt            = LocalDate.parse("2018-12-06");         // subtract 30 Days to LocalDate        LocalDate value            = zonedlt.minus(Period.ofDays(30));         // print result        System.out.println("LocalDate after"                           + " subtracting Days: "                           + value);    }}
LocalDate after subtracting Days: 2018-11-06
