Unparseable date error format in Spring Boot Mongo DB - mongodb

Question

MongoCollection<Document> Profile_List = db.getCollection("Profile_List");
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-DD");
Date todaydate = format.parse(new Date().toString());
ArrayList<Document> activeList=profile.find(Filters.regex("lastActive",todayDate.toString())).into(new ArrayList<Document>());
This is the code what we have written. We are getting an “Unparseable date error”. Can someone please help?

Answer 1

This is wrong:
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-DD");
Date todaydate = format.parse(new Date().toString());
The expression new Date().toString() does not return a string that conforms to the format yyyy-MM-DD, so if you try to parse it as if it is formatted that way, you will get an exception.
If you want a Date object that represents the current date and time, simply do this:
Date todaydate = new Date();
No need to convert the Date object to a string and trying to parse it.
If you need a string with the current date in the format yyyy-MM-dd then do this:
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
String todaydate = format.format(new Date());
Note: You used DD in your date format string but you most likely meant dd. See the API documentation of SimpleDateFormat.

Answer 2

If you are trying to get the current date string in yyyy-MM-dd format. You can do format it like this
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd");
String dateString = simpleDateFormat.format(new Date());
