The format() method of a LocalTime class is used to format this time using the specified formatter passed as a parameter. This method formats this time based on passed formatter to a string.
Syntax:
public String format(DateTimeFormatter formatter)
Parameters: This method accepts a single parameter formatter which is the specified formatter. It should not be null.
Return value: This method returns the formatted time string.
Exception: This method throws a DateTimeException if an error occurs during printing.
Below programs illustrate the format() method:
Program 1:
// Java program to demonstrate // LocalTime.format() method import java.time.*;
import java.time.format.DateTimeFormatter;
public class GFG {
public static void main(String[] args)
{
// create a LocalTime Objects
LocalTime time
= LocalTime.parse( "03:18:23" );
// create formatter Object
DateTimeFormatter formatter
= DateTimeFormatter.ISO_TIME;
// apply format
String value = time.format(formatter);
// print result
System.out.println( "value : "
+ value);
}
} |
Output:
value : 03:18:23
Program 2:
// Java program to demonstrate // LocalTime.format() method import java.time.*;
import java.time.format.DateTimeFormatter;
public class GFG {
public static void main(String[] args)
{
// create a LocalTime Objects
LocalTime time
= LocalTime.parse( "23:59:59" );
// create formatter Object for ISO_LOCAL_TIME
DateTimeFormatter formatter
= DateTimeFormatter.ISO_LOCAL_TIME;
// apply format
String value = time.format(formatter);
// print result
System.out.println( "value : "
+ value);
}
} |
Output:
value : 23:59:59
