Java 中的 Minguo 年表 resolveDate()方法，示例
原文:https://www . geeksforgeeks . org/Minguo 年表-resolved ate-method-in-Java-with-example/
Java . time . chrono . Minguo 年表类的resolved date()方法用于通过在特定的解析器样式的帮助下解析与地图中特定长值相关联的时间字段来根据民国日历检索民国日期。
语法:
public MinguoDate resolveDate(
Map fieldValues,
ResolverStyle resolverStyle)
参数:该方法将以下参数作为参数:
- Field value: This will contain the timing field.
- Parser Style: This will parse the time field and provide the date.
返回值:该方法通过解析地图中特定长值关联的 Chrono 字段，借助特定解析器样式，根据民国日历返回本地日期。
以下示例说明了 resolveDate() 方法:
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);
}
}
}
输出:
MinguoDate is : Minguo ROC 59-01-31
例 2:
// 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.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);
}
}
}
输出:
MinguoDate is : null
