Java JapaneseDate range()用法及代碼示例

使用java.time.chrono.JapaneseDate類的range()方法從TemporalField類型的指定字段獲取範圍。

用法:

public ValueRange range(TemporalField field)

參數：此方法將TemporalField類型的字段作為要獲取其範圍的參數。

返回值：此方法以ValueRange的形式返回指定字段的範圍。

下麵的示例說明了range()方法：

範例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 
            // JapaneseDate Object 
            JapaneseDate hidate = JapaneseDate.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); 
        } 
    } 
}

輸出：

Equivalent Range:-1 - 2

範例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 
            // JapaneseDate Object 
            JapaneseDate hidate = JapaneseDate.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); 
        } 
    } 
}

輸出：

Equivalent Range:1873 - 999999999
