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);    }} |
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);    }} |
value : 23:59:59
