Java中的 ChronoZonedDateTime toLocalDate() 方法及示例

ChronoZonedDateTime类的toLocalDate()方法用于将此 ChronoZonedDateTime 转换为 LocalDate。

句法:

default LocalDate toLocalDate()

参数:此方法不接受任何参数。

返回值:此方法返回LocalDate ,与此 ChronoZonedDateTime 表示的 LocalDate 相同。

下面的程序说明了 toLocalDate() 方法:

方案一:

// Java program to demonstrate
// ChronoZonedDateTime.toLocalDate() 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("LocalDate: "
                           + time.toLocalDate());
    }
}
输出:
ChronoZonedDateTime: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta]
LocalDate: 2018-12-06

方案二:

// Java program to demonstrate
// ChronoZonedDateTime.toLocalDate() 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("LocalDate: "
                           + time.toLocalDate());
    }
}
输出:
ChronoZonedDateTime: 1918-10-25T23:12:38.543Z[Europe/Paris]
LocalDate: 1918-10-25
