MinguoChronology date(int, int, int) Java中的方法与示例

Java.time.chrono.MinguoChronology类的date()方法用于根据民国日历系统获取给定年月日的本地日期。
句法：

public MinguoDate date(int prolepticYear,
                       int month,
                       int dayOfMonth)

参数：此方法将以下参数作为参数。

• prolepticYear: MinguoDate 的 year 字段的整数预测年份
• 月份： MinguoDate的月份字段的整数月份
• day： MinguoDate 的 day 字段的整数天

返回值：该方法根据民国历系统返回给定年月日的当地日期。
异常：如果给定的日、月和年字段无法形成结构化日期，则此方法抛出DateTimeException 。
以下是说明date()方法的示例：
示例 1：

Java

// Java program to demonstrate
// date() 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 MinguoDate for the
            // given date, month and year field
            // by using date() method
            MinguoDate date = crono.date(2040, 05, 24);
 
            // 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 2040-05-24

示例 2：

Java

// Java program to demonstrate
// date() 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 MinguoDate for the
            // given date, month and year field
            // by using date() method
            MinguoDate date
                = crono.date(2040, 05, -24);
 
            // 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

passed parameter can not form a date
Exception thrown: java.time.DateTimeException: Invalid value for DayOfMonth (valid values 1 - 28/31): -24
