ChronoPeriod plus() method in Java with Examples
The plus() method of ChronoPeriod interface in Java is used to add the given amount of period to the specified period. This function operates separately on YEAR, MONTH and DAY.
Note: Normalization is not performed. 12 months and 1 year are different.
Syntax:
ChronoPeriod plus(TemporalAmount amountToAdd)
Parameters: This function accepts a single parameter amountToAdd, which is amount to add to period. It must not be null.
Returns Value This function returns a ChronoPeriod based on the given period with the requested period added, and this must not be null.
Exceptions:
- DateTimeException: This exception is returned if the specified amount has a non-ISO chronology or contains an invalid unit.
- ArithmeticException: This exception is caught if numeric overflow occurs.
Below programs illustrate the above method:
Program 1:
// Java code to show the function plus() // to subtract the two given periods import java.time.*; import java.time.chrono.*; import java.time.temporal.ChronoUnit; public class ChronoPeriodDemo { // Function to subtract two given periods static void addChronoPeriod(ChronoPeriod p1, ChronoPeriod p2) { System.out.println(p1.plus(p2)); } // Driver Code public static void main(String[] args) { // Defining first period int year = 4 ; int months = 11 ; int days = 10 ; ChronoPeriod p1 = Period.of(year, months, days); // Defining second period int year1 = 2 ; int months1 = 7 ; int days1 = 8 ; ChronoPeriod p2 = Period.of(year1, months1, days1); addChronoPeriod(p1, p2); } } |

Program 2: ChronoPeriod can be negative.
// Java code to show the function plus() // to subtract the two given periods import java.time.*; import java.time.chrono.*; import java.time.temporal.ChronoUnit; public class ChronoPeriodDemo { // Function to add two given periods static void addChronoPeriod(ChronoPeriod p1, ChronoPeriod p2) { System.out.println(p1.plus(p2)); } // Driver Code public static void main(String[] args) { // Defining second period int year1 = 2 ; int months1 = 7 ; int days1 = 8 ; ChronoPeriod p1 = Period.of(year1, months1, days1); // Defining first period int year = 4 ; int months = 11 ; int days = 10 ; ChronoPeriod p2 = Period.of(year, months, days); addChronoPeriod(p1, p2); } } |
