String to Date

I am having a problem converting a string to a Java Date...

as far as i remember i have always done it like this :

SimpleDateFormat dateFormat = new SimpleDateFormat("dd.MM.yy");
Date date = dateFormat.parse("1.1.2001");

but it seems not to work.
I have searched and found several examples and always get the same error:

Unhandle exception type ParceException...

any ideas ?

Simply wrap the call to parse() within a try-catch clause:

try {
Date date = dateFormat.parse("1.1.2010");
println(date);
}
catch(ParseException e) {
println(e.getMessage());
}

IIRC this always was like that & I don't think this has changed behaviour recently... What else should it do if you try to parse a non-date string?

you are right, i remember using try/catch, just forgot about it.
hmmm dont know what it should do if it parses a non-date string, cause this probably wont happen, or at least shouldnt in my case...

Thanks for your help!

That's the problem with checked exceptions (that you have to catch or rethrow), which, to my knowledge, only Java language has - more advanced languages like Scala just dropped them: you have to catch them even if you are absolutely sure there won't be any problem with the operation (converting a string, building an URL..., when they are constants).
The println() of the message (or e.printStackTrace()) is enough in this case, still showing something is done in case of problem, but not in the way.
