The plus() method of java.time.chrono.JapaneseDate class is used to get the Japanese date after adding an amount of temporal accessor unit with the current Japanese date. Syntax:
public JapaneseDate plus(long amountToAdd,
TemporalUnit unit)
Parameter: This method takes the following argument as a parameter:
- amountToAdd: which is the amount of temporal unit which is going to be added with the current japanese date.
- unit: which is the object of temporal unit or chrono unit.
Return Value: This method returns the japanese date after adding an amount of temporal accessor unit with the current japanese date. Below are the examples to illustrate the plus() method: Example 1:
// 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
// JapaneseDate Object
JapaneseDate hidate
= JapaneseDate.of(
4000, 06, 23);
// Display the result
System.out.println(
"Old Japanese date: "
+ hidate);
// Adding some amount in Japanese date
// by using plus() method
JapaneseDate newdate
= hidate.plus(
22,
ChronoUnit.DAYS);
// Display the result
System.out.println(
"New Japanese date: "
+ newdate);
}
catch (DateTimeException e) {
System.out.println(
"Passed parameter can"
+ " not form a date");
System.out.println(
"Exception thrown: "
+ e);
}
}
}
Output:
Old Japanese date: Japanese Heisei 2012-06-23 New Japanese date: Japanese Heisei 2012-07-15
