Java中的 MinguoChronology resolveDate() 方法示例

Java.time.chrono.MinguoChronology类的resolveDate()方法用于通过在特定解析器样式的帮助下解析与地图中特定长值关联的chrono 字段，根据民国日历检索民国日期。

句法：

public MinguoDate resolveDate(
       Map fieldValues,
       ResolverStyle resolverStyle)

参数：此方法将以下参数作为参数：

• fieldvalues：这将包含计时字段。
• resolverStyle：这将解析 chrono 字段并提供日期。

返回值：该方法在特定解析器样式的帮助下，通过解析与地图中特定长值关联的 Chrono 字段，根据民国日历返回本地日期。

以下是说明resolveDate()方法的示例：

示例 1：

// Java program to demonstrate
// resolveDate() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;
import java.time.format.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        try {
            // creating and initializing
            // MinguoDate Object
            MinguoDate hidate
                = MinguoDate.now();
  
            // getting  MinguoChronology
            // used in  MinguoDate
            MinguoChronology crono
                = hidate.getChronology();
  
            // creating and initializing HashMap
            HashMap map
                = new HashMap();
  
            // putting element into HashMap
            map.put((TemporalField)
                        ChronoField.EPOCH_DAY,
                    30l);
  
            // getting the resolveDate with
            // SMART ResolverStyle
            // by using resolveDate() method
            hidate
                = crono.resolveDate(
                    map,
                    ResolverStyle.LENIENT);
  
            // display the result
            System.out.println("MinguoDate is : "
                               + hidate);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

输出：

MinguoDate is : Minguo ROC 59-01-31

            // display the result
            System.out.println("MinguoDate is : "
                               + hidate);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

输出：

MinguoDate is : null
