范例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 
            // 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); 
        } 
    } 
}

输出：

Old Japanese date:Japanese Heisei 2012-06-23
New Japanese date:Japanese Heisei 2012-07-15
