Why doesn't parsing using SimpleDateFormat produces expected results?

One reason can be...

by default SimpleDateFormat parses strings in a lenient way. However, this may result in unexpected output. And, in occasions where parsing is used as a mechanism of enforcing date format validation, lenient parsing may parse a date which is in an invalid format.

To avoid this, lenient parsing should be switched off as follows:

DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd");
