ChronoField isTimeBased() method in Java with Examples

The isTimeBased() method of ChronoField enum is used to check that if this ChronoField represents a component of a time or not.ChronoField constants from nano-of-second to am-pm-of-day are time-based.

Syntax:

public boolean isTimeBased()

Parameters: This method accepts nothing.

Return value: This method returns true if it is a component of a time.

Below programs illustrate the ChronoField.isTimeBased() method:
Program 1:

// Java program to demonstrate
// ChronoField.isTimeBased() 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 isTimeBased()
        boolean isTimeBasedAttribute
            = chronoField.isTimeBased();

        // print
        System.out.println(
            "HOUR_OF_DAY"
            + " is Time based attribute:"
            + isTimeBasedAttribute);
    }
}

Output:

HOUR_OF_DAY is Time based attribute:true

Program 2:

// Java program to demonstrate
// ChronoField.isTimeBased() 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 isTimeBased()
        boolean isTimeBasedAttribute
            = chronoField.isTimeBased();

        // print
        System.out.println("YEAR_OF_ERA"
                           + " is Time based attribute:"
                           + isTimeBasedAttribute);
    }
}

Output:

YEAR_OF_ERA is Time based attribute:false
