IsoChronology dateEpochDay() method in Java with Example
The dateEpochDay() method of java.time.chrono.IsoChronology class is used to get the local date according to ISO system from Epoch Day.
Syntax:
public IsoDate dateEpochDay(long epochDay)
Parameter: This method takes the epochDay of type long as a parameter.
Return Value: This method returns the IsoDate according to Hijrah calendar system from another TemporalAccessor object.
Below are the examples to illustrate the dateEpochDay() method:
Example 1:
Java
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] argv)
{
try {
LocalDate hidate = LocalDate.now();
IsoChronology crono = hidate.getChronology();
System.out.println( "current LocalDate is: "
+ hidate);
hidate = crono.dateEpochDay( 23456 );
System.out.println( "\nLocalDate(according "
+ "to epochday) is: "
+ hidate);
}
catch (DateTimeException e) {
System.out.println( "passed parameter can"
+ " not form a date" );
System.out.println( "Exception thrown: " + e);
}
}
}
|
Output
current LocalDate is: 2023-01-28
LocalDate(according to epochday) is: 2034-03-22
Example 2:
Java
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] argv)
{
try {
LocalDate hidate = LocalDate.of( 00000 , 01 , 01 );
IsoChronology crono = hidate.getChronology();
System.out.println( "current LocalDate is: "
+ hidate);
hidate = crono.dateEpochDay(- 999999999 );
System.out.println( "\nLocalDate(according "
+ "to epochday) is: "
+ hidate);
}
catch (DateTimeException e) {
System.out.println( "passed parameter can"
+ " not form a date" );
System.out.println( "Exception thrown: " + e);
}
}
}

Output
current LocalDate is: 0000-01-01
LocalDate(according to epochday) is: -2735938-12-30
