java.lang.String cannot be cast to java.util.Date

This error occurs when you try to cast a String object to a Date object using the Java typecasting operator. It is not possible to convert a String object to a Date object directly.

To convert a String to a Date object, you need to use the SimpleDateFormat class or another Date parsing library. For example:

String dateString = "2022-05-30";
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
Date date = format.parse(dateString);

This will create a Date object from the dateString string using the specified date format.
