Java中的 JapaneseDate toString() 方法与示例

Java.time.chrono.JapaneseDate类的toString()方法用于将日本日期表示为字符串格式。句法：

public String toString()

参数：此方法不接受任何参数作为参数。返回值：此方法将日本日期返回为字符串格式。下面是说明toString()方法的示例：示例 1：

Java

// Java program to demonstrate
// toString() 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.now();
 
            // Getting string representation
            // of Japanese date
            // by using toString() method
            String date = hidate.toString();
 
            // Display the result
            System.out.println("Japanesedate : "
                               + date);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

输出：

Japanesedate : Japanese Heisei 32-04-13

示例 2：

Java

// Java program to demonstrate
// toString() 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(2008, 05, 23);
 
            // Getting string representation
            // of Japanese date
            // by using toString() method
            String date = hidate.toString();
 
            // Display the result
            System.out.println("Japanesedate : "
                               + date);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

输出：
