Last Updated :
15 Feb, 2020
The resolveDate() method of java.time.chrono.HijrahChronology class is used to retrieve the local date according to Islamic hijri calendar by parsing chrono field associated with a particular long value in a map with the help of particular resolver style.
Syntax:
public HijrahDate resolveDate(Map fieldValues,
ResolverStyle resolverStyle)
Parameter: This method takes the following argument as a parameter:
- fieldvalues: this will contain the chrono fields.
- resolverStyle: this will resolve the chrono field and provide the date.
Return Value: This method returns the local date according to Islamic Hijri calendar by parsing Chrono field associated with a particular long value in a map with the help of particular resolver style.
Below are the examples to illustrate the resolveDate() method:
Example 1:
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 {
HijrahDate hidate
= HijrahDate.now();
HijrahChronology crono
= hidate.getChronology();
HashMap<TemporalField, Long> map
= new HashMap<TemporalField, Long>();
map.put((TemporalField)ChronoField
.EPOCH_DAY,
1000l);
map.put((TemporalField)ChronoField
.HOUR_OF_AMPM,
2000l);
map.put((TemporalField)ChronoField
.HOUR_OF_DAY,
3000l);
hidate
= crono.resolveDate(
map,
ResolverStyle.SMART);
System.out.println( "HijrahDate is : "
+ hidate);
}
catch (DateTimeException e) {
System.out.println( "passed parameter can"
+ " not form a date" );
System.out.println( "Exception thrown: "
+ e);
}
}
}
|
Output:
HijrahDate is : Hijrah-umalqura AH 1392-08-19
Example 2:
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 {
HijrahDate hidate
= HijrahDate.now();
HijrahChronology crono
= hidate.getChronology();
HashMap<TemporalField, Long> map
= new HashMap<TemporalField, Long>();
map.put((TemporalField)
ChronoField.HOUR_OF_AMPM,
2000l);
hidate
= crono.resolveDate(
map,
ResolverStyle.LENIENT);
System.out.println( "HijrahDate is : "
+ hidate);
}
catch (DateTimeException e) {
System.out.println( "passed parameter can"
+ " not form a date" );
System.out.println( "Exception thrown: "
+ e);
}
}
}

Output:
HijrahDate is : null
