Java 中的 time zoneddatetime to localdatetime()方法,带示例
原文:https://www . geeksforgeeks . org/chronozoneddatetime-tolocaldatetime-method-in-Java-with-examples/
一个时区数据时间接口的到 LocalDateTime() 方法用于将该时区数据时间转换为本地日期时间。
语法:
default LocalDateTime toLocalDateTime()
参数:该方法不接受任何参数。
返回值:此方法返回 LocalDateTime ,它与此 time zoneddatetime 表示的 LocalDateTime 相同。
下面的程序说明了 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
程序二:
// 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
