Problem with switches

[David Moncada]

Hello guys i'm new to this forums and I hope someone can help me, I have this switch:

String arrivalDate;
arrivalDate = "20 Nov 2013";
String input = arrivalDate;
Date d;
switch (arrivalDate) {

case "dd MMM yyyy":
d = new SimpleDateFormat("dd MMM yyyy", Locale.US).parse(input);
break;
case "dd-MMMM-yyyy":
d = new SimpleDateFormat("dd-MMMM-yyyy", Locale.US).parse(input);
break;
case "ddMMMMyyyy":
d = new SimpleDateFormat("ddMMMMyyyy", Locale.US).parse(input);
break;
case "dd-MMMM-yy":
d = new SimpleDateFormat("dd-MMMM-yy", Locale.US).parse(input);
break;
case "dd/MMMM/yy":
d = new SimpleDateFormat("dd/MMMM/yy", Locale.US).parse(input);
break;
default:
d = new SimpleDateFormat("MM/dd/yyyy", Locale.US).parse(input);
break;
}
String output = new SimpleDateFormat("MM/dd/yyyy").format(d);
System.out.println("this " + output);

}

It always go rigth to the default and well it sends me a parse error, why is this I have tryed to make it work but it doesn't thanks in advance guys

If your case statement has "dd MMM yyyy", and your input is "20 Nov 2013", those strings are not a match. one starts with a little 'd', the other starts with a digit '2'. The same is true for all your cases - it is matching on the LITERAL string you provide, not some interpretation of what your string means.

But then how can I introduce a date to compare to?

[Bear Bibeault]

The switch statement is going to do any pattern matching. Perhaps you need regular expressions to see what pattern your sting matches.

Ok I will try that thanks!
