ChronoField isDateBased() method in Java with Examples
The isDateBased() method of ChronoField enum is used to check that if this ChronoField represents a component of a date or not.ChronoField constants from day-of-week to era are date-based.
Syntax:
public boolean isDateBased()
Parameters: This method accepts nothing.
Return value: This method returns true if it is a component of a date.
Below programs illustrate the ChronoField.isDateBased() method:
Program 1:
// Java program to demonstrate// ChronoField.isDateBased() method  import java.time.temporal.ChronoField;  public class GFG {    public static void main(String[] args)    {          // get chronoField        ChronoField chronoField            = ChronoField.valueOf("HOUR_OF_DAY");          // apply isDateBased()        boolean isDateBasedAttribute            = chronoField.isDateBased();          // print        System.out.println(            "HOUR_OF_DAY"            + " is Date based attribute:"            + isDateBasedAttribute);    }} |
Output:
HOUR_OF_DAY is Date based attribute:false
Program 2:
// Java program to demonstrate// ChronoField.isDateBased() method  import java.time.temporal.ChronoField;  public class GFG {    public static void main(String[] args)    {          // get chronoField        ChronoField chronoField            = ChronoField.valueOf("YEAR_OF_ERA");          // apply isDateBased()        boolean isDateBasedAttribute            = chronoField.isDateBased();          // print        System.out.println("YEAR_OF_ERA"                           + " is Date based attribute:"                           + isDateBasedAttribute);    }} |
Output:
YEAR_OF_ERA is Date based attribute:true
