[FIXED] Java SimpleDateFormat Cannot format given Object as a Date

Issue

I am trying to convert string to date using date format and used the following code but its shows an error.

      public static Date ConvertStringtodate(String Date) throws ParseException {
            DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
            Date Teststart = dateFormat.parse(Date);
            return Teststart;
        }

        public static void main(String[]agrs) throws ParseException {
            System.out.println(ConvertStringtodate("2022.02.10 17:54:55"));
        }

Here is the error

Exception in thread "main" java.lang.IllegalArgumentException: Cannot format given Object as a Date at java.text.DateFormat.format(DateFormat.java:310) at java.text.Format.format(Format.java:157)

Solution

At the main method, you are sending date as "2022.02.10 17:54:55". However, you wrote format of the pattern as "yyyy-MM-dd hh:mm:ss". Change the pattern at the SimpleDateFormat constructor as "yyyy.MM.dd HH:mm:ss".
