下麵是說明eraOf()方法的示例：

範例1：

// Java program to demonstrate 
// eraOf() 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(); 
  
            // getting HijrahChronology 
            // used in HijrahDate 
            HijrahChronology crono 
                = hidate.getChronology(); 
  
            // getting HijrahEra for the 
            // given integer value 
            // by using eraOf() method 
            HijrahEra era = crono.eraOf(1); 
  
            // display the result 
            System.out.println("HijrahEra is:"
                               + era); 
        } 
        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 
// eraOf() 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(); 
  
            // getting HijrahChronology 
            // used in HijrahDate 
            HijrahChronology crono 
                = hidate.getChronology(); 
  
            // getting HijrahEra for the 
            // given integer value 
            // by using eraOf() method 
            HijrahEra era = crono.eraOf(0); 
  
            // display the result 
            System.out.println("HijrahEra is:"
                               + era); 
        } 
        catch (DateTimeException e) { 
            System.out.println("HijrahEra is invalid"); 
            System.out.println("Exception thrown:" + e); 
        } 
    } 
}

輸出：

HijrahEra is invalid
Exception thrown:java.time.DateTimeException:invalid Hijrah era
