How do I include milliseconds when formatting the current time in Java?

Retrieving Current Time with Milliseconds in Java

To retrieve the current time in the format "YYYY-MM-DD HH:MM:SS.MS," where "MS" represents milliseconds, you can use the SimpleDateFormat class. However, the code you provided uses the SimpleDateFormat without specifying the millisecond format.

To include milliseconds, you need to modify the format string as follows:

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");

Here's how this modified code works:

1. Create an instance of SimpleDateFormat with the desired format string. This code specifies the pattern "yyyy-MM-dd HH:mm:ss.SSS," where "SSS" represents milliseconds.
2. Use the format() method of the SimpleDateFormat instance to convert the current time (obtained using the Date object) to a formatted string.

With this modification, the code will return the current time in the desired format: YYYY-MM-DD HH:MM:SS.MS. For example, if the current time is 2023-03-08 14:35:23 and the milliseconds are 125, the output will be "2023-03-08 14:35:23.125."
