How to format a date String into desirable Date format

Question

I was trying to format a string into date.

For this I have written a code:-

Calendar cal = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateF         


        

Answer 1

The same class you use for output formatting of dates can also be used to parse dates on input.

• SimpleDateFormat reference

To use your example, to parse the sample date:

String dt = "2010-10-22";
SimpleDateFormat dateFormatter = new SimpleDateFormat("yyyy-MM-dd");
System.out.println(dateFormatter.parse(dt));

The fields that are not specified (ie. hour, minutes, etc) will be 0. So your same code can be used to format the date on output.
