带有示例的Java中的 HijrahDate getLong() 方法

Java.time.chrono.HijrahDate类的getLong()方法用于以长格式检索传递的时间字段。

句法：

public long getLong(TemporalField field)

参数：此方法将任何类型的时间字段作为参数。

返回值：此方法以长格式返回传递的时间字段。

以下是说明getLong()方法的示例：

示例 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

示例 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
