IsoChronology date(TemporalAccessor) method in Java with Example ❤️

The date() method of java.time.chrono.IsoChronology class is used get the local date according to ISO system from the another TemporalAccessor object.

Syntax:

public LocalDate date(TemporalAccessor temporal)

Parameter: This method takes the object of any temporal accessor as a parameter.

Return Value: This method returns the local date according to Iso calendar system from another TemporalAccessor object.

Below are the examples to illustrate the date() method:

Example 1:

// Java program to demonstrate 
// date() method 
  
import java.util.*; 
import java.io.*; 
import java.time.*; 
import java.time.chrono.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
            // creating and initializing  LocalDate Object 
            LocalDate hidate = LocalDate.now(); 
  
            // getting IsoChronology used in LocalDate 
            IsoChronology crono = hidate.getChronology(); 
  
            // creating and initializing 
            // TemporalAccessor object 
            ZonedDateTime zonedate 
                = ZonedDateTime.parse( 
                    "2018-10-25T23:12:31."
                    + "123+02:00[Europe/Paris]"); 
  
            // getting HijrahDate for the 
            // given TemporalAccessor object 
            // by using date() method 
            LocalDate date = crono.date(zonedate); 
  
            // display the result 
            System.out.println("LocalDate is: " + date); 
        } 
        catch (DateTimeException e) { 
            System.out.println("passed parameter can"
                               + " not form a date"); 
            System.out.println("Exception thrown: " + e); 
        } 
    } 
} 

Output:

LocalDate is: 2018-10-25

Example 2:

// Java program to demonstrate 
// date() method 
  
import java.util.*; 
import java.io.*; 
import java.time.*; 
import java.time.chrono.*; 
  
public class GFG { 
    public static void main(String[] argv) 
    { 
        try { 
            // creating and initializing  LocalDate Object 
            LocalDate hidate = LocalDate.now(); 
  
            // getting IsoChronology used in LocalDate 
            IsoChronology crono = hidate.getChronology(); 
  
            // creating and initializing TemporalAccessor object 
            LocalDateTime localdate 
                = LocalDateTime 
                      .parse("2018-12-30T19:34:50.63"); 
  
            // getting HijrahDate for the 
            // given TemporalAccessor object 
            // by using date() method 
            LocalDate date = crono.date(localdate); 
  
            // display the result 
            System.out.println("LocalDate is: " + date); 
        } 
        catch (DateTimeException e) { 
            System.out.println("passed parameter can"
                               + " not form a date"); 
            System.out.println("Exception thrown: " + e); 
        } 
    } 
} 

Output:

LocalDate is: 2018-12-30
