Java IsoChronology zonedDateTime(Instant, ZoneId)用法及代码示例

java.time.chrono.IsoChronology类的zonedDateTime()方法用于根据Iso calendrer从特定时刻检索特定区域的日期和时间。

用法:

public ZonedDateTime zonedDateTime(Instant instant,
                                   ZoneId zone)

参数：此方法将以下参数作为参数。

instant:这是即时类型的对象
zone:这是zoneId类型的对象

返回值：此方法根据Iso calendrer从特定瞬间返回特定区域的日期和时间。

下面是说明zonedDateTime()方法的示例：

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

输出：

LocalDate and time is:2020-03-10T02:37:13.036Z[Etc/UTC]

范例2：

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

输出：

LocalDate and time is:1970-01-01T06:56:40Z[Etc/UTC]
