import java.time.chrono.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
            // creating and initializing 
            // HijrahDate Object 
            HijrahDate hidate = HijrahDate.now(); 
  
            // getting HijrahChronology 
            // used in HijrahDate 
            HijrahChronology crono 
                = hidate.getChronology(); 
  
            // getting all HijrahEras present 
            // by using eraOf() method 
            List<Era> list = crono.eras(); 
  
            // display the result 
            System.out.println("HijrahEra is:"
                               + (list.iterator()).next()); 
        } 
        catch (DateTimeException e) { 
            System.out.println("HijrahEra is invalid"); 
            System.out.println("Exception thrown:" + e); 
        } 
    } 
}

輸出：

HijrahEra is:AH

範例2：

// 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 
            // HijrahDate Object 
            HijrahDate hidate 
                = HijrahDate.now( 
                    Clock.systemDefaultZone()); 
  
            // getting HijrahChronology 
            // used in HijrahDate 
            HijrahChronology crono 
                = hidate.getChronology(); 
  
            // getting all HijrahEras present 
            // by using eraOf() method 
            List<Era> list = crono.eras(); 
  
            // display the result 
            System.out.println("HijrahEra is:"
                               + (list.iterator()) 
                                     .next()); 
        } 
        catch (DateTimeException e) { 
            System.out.println("HijrahEra is invalid"); 
            System.out.println("Exception thrown:" + e); 
        } 
    } 
}
