Java HijrahDate range()用法及代码示例

java.time.chrono.HijrahDate类的range()方法用于从TemporalField类型的指定字段获取范围。

用法:

public ValueRange range(TemporalField field)

参数：此方法将TemporalField类型的字段作为要获取其范围的参数。

返回值：此方法以ValueRange的形式返回指定字段的范围。

下面是说明range()方法的示例：

范例1：

Java

// Java program to demonstrate 
// range() 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 the ValueRange for 
            // given ChronoField 
            // by using range() method 
            ValueRange range 
                = hidate.range(ChronoField.ERA); 
  
            // display the result 
            System.out.println("Equivalent Range:"
                               + range); 
        } 
        catch (DateTimeException e) { 
            System.out.println("passed parameter can"
                               + " not form a date"); 
            System.out.println("Exception thrown:" + e); 
        } 
    } 
}

输出：

Equivalent Range:1 - 1

范例2：

Java

// Java program to demonstrate 
// range() 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 the ValueRange for 
            // given ChronoField 
            // by using range() method 
            ValueRange range 
                = hidate.range(ChronoField.YEAR); 
  
            // display the result 
            System.out.println("Equivalent Range:"
                               + range); 
        } 
        catch (DateTimeException e) { 
            System.out.println("passed parameter can"
                               + " not form a date"); 
            System.out.println("Exception thrown:" + e); 
        } 
    } 
}

输出：

Equivalent Range:1300 - 1600
