Java HijrahChronology range()用法及代码示例

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

public ValueRange range(ChronoField field)

参数：此方法将ChronoField类型的字段作为参数。
返回值：此方法从chrono类型的指定字段返回范围。

下面是说明range()方法的示例：示例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 HijrahChronology used in HijrahDate
      HijrahChronology crono = hidate.getChronology();
 
      // getting the ValueRange for
      // given ChronoField
      // by using range() method
      ValueRange range = crono.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 HijrahChronology used in HijrahDate
      HijrahChronology crono = hidate.getChronology();
 
      // getting the ValueRange for
      // given ChronoField
      // by using range() method
      ValueRange range = crono.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
