This line of code creates a new instance of the SimpleDateFormat class (dsf) and formats the current date into a string using the specified format. The format of the string is determined by the pattern provided to the SimpleDateFormat constructor.
For example, if the pattern is "yyyy-MM-dd", the resulting string would be formatted as "2021-07-01" (assuming the current date is July 1st, 2021).
Overall, this line of code is used to convert a Date object into a formatted string representation of the date.
