  • Last Updated : 13 Dec, 2018

The format() method of OffsetTime class in Java formats this time using the specified formatter which is passed in the parameter of the function.

Syntax:

public String format(DateTimeFormatter formatter)

Parameter: This method accepts a single mandatory parameter formatter which specifies the formatter to be used and it is not null.

Return Value: It returns the formatted date string and it is not null.

Exceptions: The function returns DateTimeException which is thrown by the method when an error occurs during printing.



Below programs illustrate the format() method:

Program 1 :




// Java program to demonstrate the format() method
  
import java.time.OffsetTime;
import java.time.format.DateTimeFormatter;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // Parses the given time
        OffsetTime time
            = OffsetTime.parse("15:45:35+06:02");
  
        // Prints the parsed time
        System.out.println("Time: "
                           + time);
  
        // Function used
        DateTimeFormatter formatter
            = DateTimeFormatter.ISO_TIME;
  
        // Prints the formatted time
        System.out.println("Formatted time: "
                           + formatter.format(time));
    }
}
Output:
Time: 15:45:35+06:02
Formatted time: 15:45:35+06:02

Program 2 :




// Java program to demonstrate the format() method
  
import java.time.OffsetTime;
import java.time.format.DateTimeFormatter;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // Parses the given time
        OffsetTime time
            = OffsetTime.parse("11:14:13+07:05");
  
        // Prints the parsed time
        System.out.println("Time: "
                           + time);
  
        // Function used
        DateTimeFormatter formatter
            = DateTimeFormatter.ISO_TIME;
  
        // Prints the formatted time
        System.out.println("Formatted time: "
                           + formatter.format(time));
    }
}
Output:
Time: 11:14:13+07:05
Formatted time: 11:14:13+07:05
