I have a string like this :
that is supposed to be a date.
I need to convert it into a date like that :
How can I do that ? I tried a lot of things like converting it into a datetime and trying to format it like 'yyyy-MM-dd' but I always got this error when I run the code :
System.TypeException: Invalid date/time: 10/12/1990
Why not do it yourself using String split?
String myDate ='10/12/1990'; List<String> arrayDate = myDate.split('/'); String newDateFormat = arrayDate+'-'+arrayDate+'-'+arrayDate; System.debug(newDateFormat);
If you're located in an org that uses the MM/DD/YYYY date format, the
Date.parse() method will do the hard work for you to convert your string into a Date instance. Then, you can use
DateTime.format() to render the output format you desire. (Oddly,
DateTime has more functionality than
Date for this purpose).
Date myDate = Date.parse('10/12/1990'); System.debug( DateTime.newInstance(myDate, Time.newInstance(0, 0, 0, 0)).format('YYYY-MM-dd') );
