I have some data's like 2014-06-11T22:22:17

which i am matching using regex ([\d-])+T([\d:])+ in two different part by separating date and time like

2014-06-11 and 22:22:17 so i have created two groups

but when i am extracting the data like as below

Date =m.group(1);

it extract only digit "1" in Date String, why is it not extracting the entire group which is 2014-06-11?

    You have to repeat the character class instead of the capturing group. [\d-]+ Repeating the group will give you the value of the last iteration, and findall will return the group which will then contain a single value. Commented Nov 6, 2019 at 13:30

    Why not write the whole pattern? (\d{4}-\d{2}-\d{2})T(\d{2}:\d{2}:\d{2}) Commented Nov 6, 2019 at 13:32

I would like to use LocalDateTime in your case to get the date and time separately like this :

LocalDateTime dateTime = LocalDateTime.parse("2014-06-11T22:22:17"); LocalDate date = dateTime.toLocalDate(); // 2014-06-11 LocalTime time = dateTime.toLocalTime(); // 22:22:17
