The eras() method of java.time.chrono.IsoChronology class is used to retrieve all the eras comes under this particular Iso chronology.
Syntax:
public List eras()
Parameter: This method does not accept any argument as a parameter.
Return Value: This method returns all the eras comes under this particular Iso chronology.
Below are the examples to illustrate the eras() method:
Example 1:
Java
// Java program to demonstrate // eras() method import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] argv)
{
try {
// creating and initializing
// LocalDate Object
LocalDate hidate = LocalDate.now();
// getting IsoChronology
// used in LocalDate
IsoChronology crono
= hidate.getChronology();
// getting all IsoEras present
// by using eras() method
List<Era> list = crono.eras();
// display the result
System.out.println("IsoEra is: "
+ (list.iterator()).next());
}
catch (DateTimeException e) {
System.out.println("IsoEra is invalid");
System.out.println("Exception thrown: " + e);
}
}
} |
Output:
IsoEra is: BCE
Example 2:
Java
// Java program to demonstrate // eras() method import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] argv)
{
try {
// creating and initializing
// LocalDate Object
LocalDate hidate = LocalDate.now();
// getting IsoChronology
// used in LocalDate
IsoChronology crono
= hidate.getChronology();
// getting all IsoEras present
// by using eras() method
List<Era> list = crono.eras();
// getting list Iterator
Iterator iter = list.iterator();
// display the result
System.out.println("List of IsoEra : "
+ "\n"
+ iter.next() + "\n"
+ iter.next());
}
catch (DateTimeException e) {
System.out.println("IsoEra is invalid");
System.out.println("Exception thrown: " + e);
}
}
} |
Output:
List of IsoEra : BCE CE
