以下是说明dateNow()方法的示例：

示例 1：

// Java program to demonstrate
// MinguoNow() 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();
  
            // creating and initializing
            // clock object
            Clock clock = Clock.systemUTC();
  
            // getting MinguoDate for the
            // given clock object
            // by using dateNow() method
            MinguoDate date
                = crono.dateNow(clock);
  
            // display the result
            System.out.println(
                "MinguoDate is: "
                + date);
        }
        catch (DateTimeException e) {
            System.out.println(
                "passed parameter can "
                + "not form a date");
            System.out.println(
                "Exception thrown: " + e);
        }
    }
}

输出：

MinguoDate is: Minguo ROC 109-04-15

示例 2：

            MinguoChronology crono
                = hidate.getChronology();
  
            // creating and initializing
            // clock object
            Clock clock = Clock.systemUTC();
  
            // setting clock
            clock = Clock.tick(
                clock,
                Duration.ofDays(100));
  
            // getting MinguoDate for the
            // given clock object
            // by using dateNow() method
            MinguoDate date
                = crono.dateNow(clock);
  
            // display the result
            System.out.println(
                "MinguoDate is: "
                + date);
        }
        catch (DateTimeException e) {
            System.out.println(
                "passed parameter can "
                + "not form a date");
            System.out.println(
                "Exception thrown: " + e);
        }
    }
}

输出：

MinguoDate is: Minguo ROC 109-02-08
