Joda time invalid format

there's an error when I try to execute this code with Joda time:

// yyyy-mm-dd, also tried 17-Feb-2013
String input = "2013-02-17";

DateTimeFormatter formatter = DateTimeFormat.forPattern("dd/MM/yyyy");
DateTime dt = formatter.parseDateTime(input);

TextView tv = (TextView) findViewById(R.id.tvShow);
tv.setText("HERE >>> " + dt.toString());

any ideas?

logcat says:

You've asked it to parse "2013-02-17" as if it were in the format "dd/MM/yyyy", which it's clearly not.

You need to specify yyyy-MM-dd as the pattern:

DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd");

Or if you need dd/MM/yyyy as the pattern, you need to provide it text of that form, e.g.

String input = "17/02/2013";

Either way, the data you're providing has to match the format you're specifying. That's the whole point of specifying the format, after all.

See the docs for DateTimeFormat for what the various letters in the format pattern mean.

You are not suppose to make a confusion in the format

Option 1

String input = "2013-02-17";

DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd"); DateTime dt = formatter.parseDateTime(input);

TextView tv = (TextView) findViewById(R.id.tvShow); tv.setText("HERE >>> " + dt.toString());

Option 2

String input = "17/02/2013";

DateTimeFormatter formatter = DateTimeFormat.forPattern("dd/MM/yyyy"); DateTime dt = formatter.parseDateTime(input);

TextView tv = (TextView) findViewById(R.id.tvShow); tv.setText("HERE >>> " + dt.toString());

Try this code u input wrong date format.

String input = "17/02/2013";

DateTimeFormatter formatter = DateTimeFormat.forPattern("dd/MM/yyyy");
DateTime dt = formatter.parseDateTime(input);
