MinguoDate minus(long, TemporalUnit) method in Java with Example
  • Last Updated : 24 Apr, 2020

The minus() method of java.time.chrono.MinguoDate class is used to get the Minguo date after subtracting an amount of teporal accessor unit from the current Minguo date.

Syntax: 

public MinguoDate minus(long amountToAdd,
                        TemporalUnit unit)

Parameter: This method takes the following argument as a parameter:

  • amountToSubstract: which is the value of temporal unit which is going to substracted from the current Minguo date.
  • unit: which is the object of temporal unit or chrono unit.

Return Value: This method returns the Minguo date after subtracting an amount of temporal accessor unit from current Minguo date.

Below are the examples to illustrate the minus() method:

Example 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);
        }
    }
}


Output:

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

Example 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);
        }
    }
}


Output:

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