Java中的 MinguoDate range() 方法与示例

Java.time.chrono.MinguoDate类的range()方法用于从 TemporalField 类型的指定字段中获取范围。

句法：

public ValueRange range(TemporalField field)

参数：该方法将TemporalField类型的字段作为要获取其范围的参数。

返回值：该方法以ValueRange的形式返回指定字段的范围。

以下是说明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
            // MinguoDate Object
            MinguoDate hidate = MinguoDate.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 : 0 - 1

示例 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
            // MinguoDate Object
            MinguoDate hidate = MinguoDate.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 : -1000001910 - 999998088
