Java中的 MinguoChronology dateNow(ZoneId) 方法示例

Java.time.chrono.MinguoChronology类的dateNow()方法用于从指定时区的系统时钟根据民国日历系统获取当前本地日期。

句法：

public MinguoDate dateNow(ZoneId zone)

参数：该方法以zone id的对象为参数。

返回值：该方法根据民国日历系统从指定的时钟对象返回本地日期。

以下是说明dateNow()方法的示例：

示例 1：

// Java program to demonstrate
// dateNow() 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 ZoneId object
            ZoneId id = ZoneId.systemDefault();
  
            // getting MinguoDate for the
            // given zoneid object
            // by using dateNow() method
            MinguoDate date = crono.dateNow(id);
  
            // 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：

// Java program to demonstrate
// dateNow() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
  
public class GFG {

        try {
            // creating and initializing MinguoDate Object
            MinguoDate hidate = MinguoDate.now();
  
            // getting MinguoChronology used in MinguoDate
            MinguoChronology crono = hidate.getChronology();
  
            // creating and initializing ZoneId object
            ZoneId id = ZoneId.of("Europe/Paris");
  
            // getting MinguoDate for the
            // given zoneid object
            // by using dateNow() method
            MinguoDate date = crono.dateNow(id);
  
            // 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
