Java HijrahDate getLong()用法及代码示例

java.time.chrono.HijrahDate类的getLong()方法用于检索长格式传递的时间字段。

用法:

public long getLong(TemporalField field)

参数：此方法将任何类型的时域作为参数。

返回值：此方法以长格式返回传递的时间字段。

下面是说明getLong()方法的示例：

范例1：

Java

// Java program to demonstrate 
// getLong() method 
  
import java.util.*; 
import java.io.*; 
import java.time.*; 
import java.time.chrono.*; 
import java.time.temporal.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
  
            // creating and initializing 
            // HijrahDate Object 
            HijrahDate hidate = HijrahDate.now(); 
  
            // getting temporal field in long format 
            // by using getLong() method 
            long tempo 
                = hidate.getLong(ChronoField.EPOCH_DAY); 
  
            // display the result 
            System.out.println( 
                "specified temporal field"
                + "in long format:"
                + tempo); 
        } 
        catch (DateTimeException e) { 
            System.out.println("passed parameter can"
                               + " not form a date"); 
            System.out.println("Exception thrown:"
                               + e); 
        } 
    } 
}

输出：

specified temporal fieldin long format:18304

范例2：

Java

// Java program to demonstrate 
// getLong() method 
  
import java.util.*; 
import java.io.*; 
import java.time.*; 
import java.time.chrono.*; 
import java.time.temporal.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
            // creating and initializing 
            // HijrahDate Object 
            HijrahDate hidate = HijrahDate.now(); 
  
            // getting temporal field in long format 
            // by using getLong() method 
            long tempo 
                = hidate.getLong(ChronoField.DAY_OF_WEEK); 
  
            // display the result 
            System.out.println("specified temporal field"
                               + " in long format:"
                               + tempo); 
        } 
        catch (DateTimeException e) { 
            System.out.println("passed parameter can"
                               + " not form a date"); 
            System.out.println("Exception thrown:"
                               + e); 
        } 
    } 
}

输出：

specified temporal field in long format:3
