下麵的示例說明了eras()方法：

範例1：

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

輸出：

MinguoEra is:BEFORE_ROC

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 
            // MinguoDate Object 
            MinguoDate hidate 
                = MinguoDate.now(); 
  
            // getting MinguoChronology 
            // used in MinguoDate 
            MinguoChronology crono 
                = hidate.getChronology(); 
  
            // getting all MinguoEras present 
            // by using eraOf() method 
            List<Era> list = crono.eras(); 
  
            // getting list Iterator 
            Iterator iter = list.iterator(); 
  
            // display the result 
            System.out.println("List of MinguoEra:"); 
            for (int i = 0; i < 2; i++) 
                System.out.println(iter.next()); 
        } 
        catch (DateTimeException e) { 
            System.out.println( 
                "MinguoEra is invalid"); 
            System.out.println( 
                "Exception thrown:" + e); 
        } 
    } 
}

輸出：

List of MinguoEra:
BEFORE_ROC
ROC
