replacing spaces in java using replace or replaceAll [duplicate]

Question

I'm working on a java project and I need to send a date format within a URL but the container of date send it with spaces which is impossible so i convert it to a string and I used the replace method to replace the spaces with "" or "-" but it didn't work

Here is the code:

Date date = date_debut.getDate();
String dateconver= date.toString();
String datef= dateconver.replace(" ", "");

And here is the error: incompatible types string can not be converted to char

I have tried also to use replaceAll but the IDE didn't even show it

maybe you just need to encode url parameters instead of this? — AdamSkywalker

@Dali, you definitely need this: docs.oracle.com/javase/7/docs/api/java/net/URLEncoder.html — Alex Salauyou

Try this code

Date date = date_debut.getDate();
String dateconver= date.toString();
String datef= dateconver.replaceAll("\\s", "");

add Log.d("Test","String: " + dateconver); after date.toString(); and paste the Logcat error

this will remove \s occurrences (not whitespaces). To regex-based replace, use .replaceAll(). Can't understand why this answer is upvoted, as even if properly used it will produce some wierd MonMar2814:43:56AST2016
