LocalDate plus() method in Java with Examples

  • Last Updated : 18 Dec, 2018

In LocalDate class, there are two types of plus() method depending upon the parameters passed to it.

plus(long amountToAdd, TemporalUnit unit)

plus() method of a LocalDate class used to return a copy of this LocalDate with the specified amount of unit added to LocalDate.If it is not possible to add the amount, because the unit is not supported or for some other reason, an exception is thrown.This instance is immutable and unaffected by this method call.

Syntax:

public LocalDate plus(long amountToAdd,
                      TemporalUnit unit)

Parameters: This method accepts two parameters:



  • amountToAdd: which is the amount of the unit to add to the result, may be negative
  • unit: which is the unit of the amount to add.

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

Below programs illustrate the plus() method:

Program 1:




// Java program to demonstrate
// LocalDate.plus() 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");
  
        // add 300 Months to LocalDate
        LocalDate value
            = zonedlt.plus(300, ChronoUnit.MONTHS);
  
        // print result
        System.out.println("LocalDate after adding Months : "
                           + value);
    }
}
Output:
LocalDate after adding Months : 2043-12-06

plus(TemporalAmount amountToAdd)

plus() method of a LocalDate class used to return a copy of this LocalDate with the specified amount added LocalDate.The amount is typically Period or Duration but may be any other type implementing the TemporalAmount interface.

Syntax:

public LocalDate plus(TemporalAmount amountToAdd)

Parameters: This method accepts one single parameter amountToAdd which is the amount to add, It should not be null.

Return value: This method returns LocalDate based on this date-time with the addition made.

Below programs illustrate the plus() method:

Program 1:




// Java program to demonstrate
// LocalDate.plus() method
  
import java.time.*;
public class GFG {
    public static void main(String[] args)
    {
  
        // create a LocalDate object
        LocalDate zonedlt
            = LocalDate.parse("2018-12-06");
  
        // add 100 Days to LocalDate
        LocalDate value
            = zonedlt.plus(Period.ofDays(100));
  
        // print result
        System.out.println("LocalDate after adding Days: "
                           + value);
    }
}
Output:
LocalDate after adding Days: 2019-03-16
