Java ChronoZonedDateTime toLocalDateTime()方法及示例

ChronoZonedDateTime 接口的 toLocalDateTime() 方法用于将该ChronoZonedDateTime转换成LocalDateTime。

语法

default LocalDateTime toLocalDateTime()

参数： 该方法不接受任何参数。

返回值： 该方法返回 LocalDateTime ，它与ChronoZonedDateTime所代表的LocalDateTime相同。

以下程序说明了toLocalDateTime()方法。

程序1 :

// Java program to demonstrate
// ChronoZonedDateTime.toLocalDateTime() method
  
import java.time.*;
import java.time.chrono.*;
import java.time.chrono.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create ChronoZonedDateTime object
        ChronoZonedDateTime time
            = ZonedDateTime
                  .parse(
                      "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]");
  
        // print ChronoZonedDateTime
        System.out.println("ChronoZonedDateTime: "
                           + time);
  
        // print result
        System.out.println("LocalDateTime: "
                           + time.toLocalDateTime());
    }
}

输出:

ChronoZonedDateTime: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta]
LocalDateTime: 2018-12-06T19:21:12.123

程序2

// Java program to demonstrate
// ChronoZonedDateTime.toLocalDateTime() method
  
import java.time.*;
import java.time.chrono.*;
import java.time.chrono.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // create ChronoZonedDateTime object
        ChronoZonedDateTime time
            = ZonedDateTime.parse(
                "1918-10-25T23:12:38.543+02:00[Europe/Paris]");
  
        // print ChronoZonedDateTime
        System.out.println("ChronoZonedDateTime: "
                           + time);
  
        // print result
        System.out.println("LocalDateTime: "
                           + time.toLocalDateTime());
    }
}

输出:

ChronoZonedDateTime: 1918-10-25T23:12:38.543Z[Europe/Paris]
LocalDateTime: 1918-10-25T23:12:38.543
