Write a function formatSimple that returns a formatted string using the date as parameter. The awaited format is febbraio 13 22
Write a function formatIso that returns a formatted string using the time as parameter. The awaited format is 16:18:56.8495847

Expected Functions

import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.LocalTime;

public class FormatDate {

    public static String formatToFullText(LocalDateTime dateTime) {
        // your code here
    }

    public static String formatSimple(LocalDate date) {
        // your code here
    }

    public static String formatIso(LocalTime time) {
        // your code here
    }

}

Usage

Here is a possible ExerciseRunner.java to test your function :

import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.LocalTime;

public class ExerciseRunner {

    public static void main(String[] args) {
        System.out.println(FormatDate.formatToFullText(LocalDateTime.of(2021, 8, 22, 13, 25, 46)));
        System.out.println(FormatDate.formatSimple(LocalDate.of(2022, 2, 13)));
        System.out.println(FormatDate.formatIso(LocalTime.of(16, 18, 56, 8495847)));
    }
}

and its output :

$ javac *.java -d build
$ java -cp build ExerciseRunner 
Le 22 août de l'an 2021 à 13h25m et 46s
febbraio 13 22
