java.time.chrono.JapaneseChronology類的zonedDateTime()方法用於根據日語日曆從特定時刻檢索特定區域的日期和時間。

用法:

public ZonedDateTime zonedDateTime(
       Instant instant, ZoneId zone)

參數：此方法將以下參數作為參數。

instant:這是即時類型的對象
zone:這是zoneId類型的對象

返回值：此方法根據日語日曆從特定瞬間返回特定區域的ZonedDateTime。

下麵是說明zonedDateTime()方法的示例：

範例1：

// Java program to demonstrate 
// zonedDateTime() method 
  
import java.util.*; 
import java.io.*; 
import java.time.*; 
import java.time.chrono.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
            // creating and initializing 
            // JapaneseDate Object 
            JapaneseDate hidate 
                = JapaneseDate.now(); 
  
            // getting JapaneseChronology 
            // used in JapaneseDate 
            JapaneseChronology crono 
                = hidate.getChronology(); 
  
            // getting JapaneseDate and time for the 
            // given Instant and ZoneId 
            // by using zonedDateTime() method 
            ChronoZonedDateTime<JapaneseDate> date 
                = crono.zonedDateTime( 
                    Instant.now(), 
                    ZoneId.systemDefault()); 
  
            // display the result 
            System.out.println( 
                "JapaneseDate and time is:"
                + date); 
        } 
        catch (DateTimeException e) { 
            System.out.println( 
                "passed parameter can "
                + "not form a date"); 
            System.out.println( 
                "Exception thrown:" + e); 
        } 
    } 
}

輸出：

JapaneseDate and time is:
 Japanese Heisei 32-03-15T06:55:36.135Z[Etc/UTC]

範例2：

// Java program to demonstrate

            JapaneseDate hidate 
                = JapaneseDate.now(); 
  
            // getting JapaneseChronology 
            // used in JapaneseDate 
            JapaneseChronology crono 
                = hidate.getChronology(); 
  
            // getting JapaneseDate and time for the 
            // given Instant and ZoneId 
            // by using zonedDateTime() method 
            ChronoZonedDateTime<JapaneseDate> date 
                = crono.zonedDateTime( 
                    Instant.ofEpochSecond(25000), 
                    ZoneId.systemDefault()); 
  
            // display the result 
            System.out.println( 
                "JapaneseDate and time is:"
                + date); 
        } 
        catch (DateTimeException e) { 
            System.out.println( 
                "passed parameter can "
                + "not form a date"); 
            System.out.println( 
                "Exception thrown:" + e); 
        } 
    } 
}

輸出：

JapaneseDate and time is:
 Japanese Showa 45-01-01T06:56:40Z[Etc/UTC]
