Java MinguoDate minus(long, TemporalUnit)用法及代碼示例

java.time.chrono.MinguoDate類的minus()方法用於在從當前Minguo日期中減去一定數量的詞性訪問器單位後獲取Minguo日期。

用法:

public MinguoDate minus(long amountToAdd,
                        TemporalUnit unit)

參數：此方法將以下參數作為參數：

amountToSubstract:這是將從當前Minguo日期減去的時間單位的值。
unit:這是時間單位或計時單位的對象。

返回值：此方法從當前的Mining日期減去臨時訪問者單位的數量後返回Minguo日期。

下麵是說明minus()方法的示例：示例1：

Java

// Java program to demonstrate minus() 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.now(); 
  
            // Display the result 
            System.out.println("old Minguo date:"
                               + hidate); 
  
            // Substracting Minguo date 
            // by using minus() method 
            MinguoDate newdate 
                = hidate.minus( 
                    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); 
        } 
    } 
}

輸出：

old Minguo date:Minguo ROC 109-04-24
new Minguo date:Minguo ROC 109-04-02

範例2：

Java

// Java program to demonstrate minus() 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.now(); 
  
            // Display the result 
            System.out.println("old Minguo date:"
                               + hidate); 
  
            // Substracting Minguo date 
            // by using minus() method 
            MinguoDate newdate 
                = hidate.minus( 
                    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); 
        } 
    } 
}

輸出：

old Minguo date:Minguo ROC 109-04-24
new Minguo date:Minguo ROC 69-04-24
