Java中的 ThaiBuddhistChronology resolveDate() 方法与示例

Java.time.chrono.ThaiBuddhistChronology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 long 值相关联的 chrono 字段，根据 ThaiBuddhist 日历检索 ThaiBuddhist 日期。

句法：

public ThaiBuddhistDate 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：此方法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 ThaiBuddhist 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
            // ThaiBuddhistDate Object
            ThaiBuddhistDate hidate
                = ThaiBuddhistDate.now();
  
            // getting  ThaiBuddhistChronology
            // used in  ThaiBuddhistDate
            ThaiBuddhistChronology 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("ThaiBuddhistDate is : "
                               + hidate);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

输出：

ThaiBuddhistDate is : ThaiBuddhist BE 2513-01-31

        }
        catch (DateTimeException e) {

                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

输出：

ThaiBuddhistDate is : null
