Java MinguoChronology resolveDate()用法及代碼示例

java.time.chrono.MinguoChronology類的resolveDate()方法用於通過根據特定解析器樣式解析與Map中特定long值相關聯的chrono字段來根據Minguo日曆來檢索Minguo日期。

用法:

public MinguoDate resolveDate(
       Map fieldValues,
       ResolverStyle resolverStyle)

參數：此方法將以下參數作為參數：

fieldvalues:這將包含計時字段。
resolverStyle:這將解決計時字段並提供日期。

返回值：此方法通過使用特定解析器樣式來解析與Map中特定long值相關聯的Chrono字段，從而根據Minguo日曆返回本地日期。

下麵的示例說明了resolveDate()方法：

範例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<TemporalField, Long> map 
                = new HashMap<TemporalField, Long>(); 
  
            // 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); 
        } 
    } 
}

輸出：

MinguoDate is:Minguo ROC 59-01-31

            map.put((TemporalField) 
                        ChronoField.HOUR_OF_AMPM, 
                    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); 
        } 
    } 
}

輸出：

MinguoDate is:null
