MinguoDate plus(long, TemporalUnit) 方法在Java中的示例

Java.time.chrono.MinguoDate类的plus()方法用于在与当前民国日期相加一定数量的时间存取单元后得到民国日期。

句法：

public MinguoDate plus(long amount,
                       TemporalUnit unit)

参数：此方法将以下参数作为参数：

• 数量：这是要与当前民国日期相加的时间单位数量。
• 单位：这是时间单位或计时单位的对象。

返回值：该方法在与当前民国日期相加一定数量的时间存取单元后返回民国日期。

以下是说明plus()方法的示例：

示例 1：

Java

// Java program to demonstrate
// plus() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        try {
            // creating and initializing
            // MinguoDate Object
            MinguoDate hidate
                = MinguoDate.of(1345, 06, 23);
  
            // display the result
            System.out.println("old Minguo date : "
                               + hidate);
  
            // adding some amount in Minguo date
            // by using minus() method
            MinguoDate newdate
                = hidate.plus(
                    22,
                    ChronoUnit.DAYS);
  
            // display the result
            System.out.println("new Minguo date : "
                               + newdate);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

输出：

old Minguo date : Minguo ROC 1345-06-23
new Minguo date : Minguo ROC 1345-07-15

            MinguoDate hidate
                = MinguoDate.of(1345, 06, 23);
  
            // display the result
            System.out.println("old Minguo date : "
                               + hidate);
  
            // adding some amount in Minguo date
            // by using minus() method
            MinguoDate newdate
                = hidate.plus(
                    4,
                    ChronoUnit.DECADES);
  
            // display the result
            System.out.println("new Minguo date : "
                               + newdate);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

输出：

old Minguo date : Minguo ROC 1345-06-23
new Minguo date : Minguo ROC 1385-06-23
