How to get current date and time in format YYYY-MM-DD HH:MM:SS.milliseconds in Java?

Hello everyone! I'm a beginner in Java and writing a small application for event logging. I need to write the current time with millisecond precision to a file in the format: `2023-11-15 14:30:25.123`. I tried using `java.util.Date` and `SimpleDateFormat`, but something is going wrong. Here's my code: ```java import java.util.Date; import java.text.SimpleDateFormat; public class Main { public static void main(String[] args) { Date now = new Date(); SimpleDateFormat sdf = new SimpleDateFormat("YYYY-MM-DD HH:MI:SS.mmm"); String formattedDate = sdf.format(now); System.out.println(formattedDate); } } ``` The output I get is something strange: `2023-11-335 14:09:25.025`. Where does `335` come from instead of the day of the month? And why are minutes displayed as `MI`?
