The subtractFrom(Temporal) method of ChronoPeriod Interface in java.time.chrono package is used subtract this ChronoPeriod to the specified temporal object, passed as the parameter.
Syntax:
Temporal subtractFrom(Temporal temporalObject)
Parameters: This method accepts a parameter temporalObject which is the amount to be adjusted in this ChronoPeriod. It should not be null.
Return Value: This method returns an object of the same type with the temporalObject adjusted to it.
Exception: This method throws:
- DateTimeException: if unable to subtract.
- ArithmeticException: if numeric overflow occurs.
Below examples illustrate the ChronoPeriod.subtractFrom() method:
Program 1:
// Java code to show the function subtractFrom()// to subtract the two given periods import java.time.*;import java.time.chrono.*;import java.time.temporal.ChronoUnit; public class ChronoPeriodDemo { // Driver Code public static void main(String[] args) { // Defining period int year = 4; int months = 11; int days = 10; ChronoPeriod p1 = Period.of(year, months, days); // Get the time to be adjusted LocalDateTime currentTime = LocalDateTime.now(); // Adjust the time // using subtractFrom() method System.out.println( p1.subtractFrom(currentTime)); }} |
Output:
2014-07-07T14:22:21.929
Program 2:
// Java code to show the function subtractFrom()// to subtract the two given periods import java.time.*;import java.time.chrono.*;import java.time.temporal.ChronoUnit; public class ChronoPeriodDemo { // Driver Code public static void main(String[] args) { // Defining period int year1 = 2; int months1 = 7; int days1 = 8; ChronoPeriod p1 = Period.of(year1, months1, days1); // Get the time to be adjusted LocalDateTime currentTime = LocalDateTime.now(); // Adjust the time // using subtractFrom() method System.out.println( p1.subtractFrom(currentTime)); }} |
Output:
