√java string to date time format

Date time format: Yyyy-mm-dd hh:mm:ss
String time = "1900-02-21 12:23:33";
Converts a string to a date and time
SimpleDateFormat DateFormat = new SimpleDateFormat ("Yyyy-mm-dd hh:mm:ss");
Date and time of the build
Date date = DateFormat. Parse (time);

Date is what we want.

If there are 2 or more places in your program that call the Dateformat.parse () method, you may get an error: Unhandled exception type ParseException.

To do this, you need to use the Try-catch block to capture:

try{
            DateFormat. Parse (time);
         } catch (Exception e) {
             E.printstacktrace ();
        }
