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));
}
