Exception :
Error: Unparseable date: “20121010”

Answer 1

D (Capital) is used to indicate DAY IN YEAR like 123,300,etc.

While d (small-lowercase) is used to indicate DAY OF MONTH like 12,25, Here values like 36 will not be valid.

Javadoc explains all the letters that you can use in SimpleDateFormat
